If you haven't already, be sure and check out previous articles in the series:

• Turn Your Home Router Into a Super-Powered Router with DD-WRT
• How To Install Additional Software On Your Home Router (DD-WRT)
• How to Remove Advertisements with Pixelserv on DD-WRT

Assuming you are familiar with those topics, keep reading. Keep in mind that this guide is a little more technical, and beginners should be careful when modding their router.

While Transmission isn't the only BiTorrent client that can be installed from the OpenWRT OPKG repository, due to the fact that it is the De facto standard for all the major Linux distributions (like Ubuntu and Mint for example), it is stable, actively maintained and very versatile. As part of its versatility, it can be remotely controlled by a number of programs, including at least two Windows ones and a web-interface.

In this guide, we will: Install Transmission on the router, have it load automatically on the routers boot and make it remotely controlled on your local network by a windows machine and a web-interface.

• It is assumed that you haven't reached this article at random and that you have already followed the procedures described in " How To Install Additional Software On Your Home Router (DD-WRT) ", fulfilling that guide's prerequisites in the process.
• It is strongly recommended that you connect a HardDrive(HD) to the router, and for the instructions below, it is assumed that you have.
• It is assumed that said HD is already formatted.Note: While partitioning + formatting ( 1 , 2 ) the HD is beyond the scope of this guide, because DD-WRT as of version 17798, supports all common FileSystems such as FAT32 + ext2/3 and NTFS, you shouldn't have to do anything special.

With that out of the way...

Enable UPnP

UPnP is a mechanism by which programs on your network can request the router to forward ports to them automatically. doing so will absolve you from  opening/forwarding the ports on your router to the transmission daemon on your own.

To do this, go to the router's web-gui:

• Go to "NAT/QoS" - "UPnP".
• For "UPnP Service", select the "enable" radio button.
• Save & Apply Settings.

Mount the HardDrive(HD)

If you haven't already, mount the HD using the router's web-gui. To do this, go to the router's web-gui:

• Under the "Services" tab go to the "USB" tab.
• Save & Apply Settings.

Installing the package

We will install the daemon package by  issuing from a terminal:

opkg update; opkg install transmission-daemon

Package configuration

With Transmission now installed, run the daemon once so that it creates the default settings file template for us. We will run it in the foreground (the "-f" flag) so its easier to see when its stabilized and quit once it has. Issue:

transmission-daemon -f

Once the program has been up for about 10 seconds, it should be ready to be quitted out of by hitting "Ctrl+C".

Directories

Create the directories that will hold the torrent pointers, parts, configurations and downloads. For my setup this is:

mkdir -p /mnt/sda_part1/torrents/parts/ mkdir -p /mnt/sda_part1/torrents/config/

Note: The above assumes one HD is connected to the router and that it has a partition layout with a filesystem on the first partition. While this is a very common default setup, in accordance with your HD's partitioning and formatting layout, this is subject to change.

Copy the configuration file created by the first run of the daemon:

cp /tmp/root/.config/transmission-daemon/settings.json /mnt/sda_part1/torrents/config

Note: despite representation, this is one continues line.

The command below, will add the "192.168.11.*" network to the rpc-whitelist parameter. This will allow us to connect from any computer on the local network (using the remote gui program) to the daemon on the router.

sed -i "s/127.0.0.1/127.0.0.1,192.168.11.\*/g" /mnt/sda_part1/torrents/config/settings.json

Note1: despite representation, this is one continues line.

Note2: If your network subnet  is different, you will have to adjust accordingly.

Execute the daemon again, this time direct it to use the alternative configuration directory (the "-g" flag).

transmission-daemon -f -g /mnt/sda_part1/torrents/config

You should see that the daemon has started and if you look closely, you should see that the paths used by the program have also changed to the new path. Leave the daemon open for now, we'll need it up and running for the GUI segment.

There are two Windows programs to control the daemon remotely, they are:  Transmisson-remote-gui &  Transmission-remote-dotnet . Both seem to be fully featured and actively maintained. While you may choose any one of them, we will use "transmission-remote-dotnet" for the sake of this article, because other then cosmetic differences,  they are virtually identical.

We will install the client and then use it to change the settings on the server, as it is easier then manually editing the settings file.

Configure local settings

• Download the latest Transmission-remote-dotnet  from the project's site, and install normally.
• Click on "Add Server".
• Then click on the "Server 0" name that has just been added so we can change its settings.
• In the host field put your router's IP.

Configure the remote daemon

• In the download to textbox put: "/mnt/sda_part1/torrents"
• Check the "Incomplete download to" checkbox.
• In the incomplete textbox put: "/mnt/sda_part1/torrents/parts"
• Click on "Save".

That's it, you should be able to use the program just like any other BiTorrent client you would install on your computer.

While using one of the remote-gui programs above would have been sufficient, you may want, a way to access the daemon without being bound to a program on a specific device. This is because with today's pleura of personal devices, it is becoming a daunting task to keep track of what is available where, and simply pointing a web browser to the router should be (if you're a loyal DD-WRT user) second nature to you by now. Also having a web-interface makes it really easy to add downloads while you're "on the go". While making the web-GUI publicly accessible is beyond the scope of this guide, we will show how to install and configure the web interface and you can chisel the public accessibility later.

Install the package by issuing in a terminal:

opkg update; opkg install transmission-web

Transmission will automatically look for the web interface in several default locations. We've ran transmission in a "foreground" mode (the -f flag) in the last step so you can see these locations, if you try to access  the web interface. While right now, you will fail, you will see that one of these locations is "/tmp/root/.local/share/transmission/". Fortunately for us, this location is on the routers RAM which is read-writable. So all we actually have to do, is create a symbolic link between this location in RAM to the location the web interface has been installed to as part of the package on JFFS . To do this, create the location (manually for now) by issuing:

mkdir -p /tmp/root/. local /share/transmission/

Create the symbolic link, again manually for now, by issuing:

ln -s /jffs/opt/usr/share/transmission/web/ /tmp/ root/.local/share/transmission/web

Try to access the web interface again at: http://your-router's-ip-or-dns:9091. For my setup this would be, with IP: "http://192.168.11.1:9091" or with local dns name: "http://buffalo.aviad.lan:9091".

If all went well and you add something to be downloaded, you should see something like:

Creating and using a Swap File (Optional)

A "Swap File" is just like the  Windows "Page file " and in fact in the past Microsoft used to call it a "Swap File" too. When drafting this article I've found one situation, in which the daemon, would encounter a memory leak and crash (see remarks section). To try and overcome this issue, I've setup Swap (both as a partition and as a file). While this had only served to prolong the inevitable, in regards to the memory leak, because I've already invested the effort of making this a simple to follow procedure, I see no reason, to not pass on the information.  With that said, as stated in the headline, this step is optional, and I can vouch that the daemon has been running fine for over a week straight and without interruptions while working on at least 5 different torrents. But then again, my router has 128MB of RAM (which is considered a lot in router circles) so you may have to perform this step if your router is memory starved. Also there shouldn't be a penalty if you do decide to implement Swap, despite not "needing" it, as Linux shouldn't try to use Swap just because it is there (unlike Windows).

While in Linux it is customary to use a Swap " partition ", doing so would require one to perform the partitioning before hand, or even worse,  change the current layout . As this may be inconvenient if you already have data on the HD, Using a file, on the already existing format of the drive, is much easier. Moreover I haven't found any significant difference in performance while comparing the two Swap utilization schemas.

We will create a 256MB file to work on. To do this, " DD " a file into existence by issuing in a terminal:

dd if=/dev/zero of=/mnt/sda_part1/swap.page bs=1M count=256

WARNING: This command (" DD ") is extremely powerful and potentially destructive. The "Output File" (of) directive should not be taken lightly, as an incorrect parameter here might cause you to lose data.

Install the package that would enable us to create swaps by issuing:

opkg update; opkg install swap-utils

Once the swap-utils have been installed, create the swap file by issuing:

mkswap /mnt/sda_part1/swap.page

Now test that the system is able to imply the swap file by examining the memory usage with the "free" command.

Note that the parameters in the "Swap" row are all zeros.

Now activate the swap file by issuing:

swapon /mnt/sda_part1/swap.page

And issue the free command again:

You should now see that the parameters in the "Swap" row, have changed to reflect that there is now a total of 256MB of available swap space.

Starting the daemon automatically

In order to have the Transmission daemon automatically start with the router's reboot, one only needs to add it to the "geek-init" script which has been installed in the OPKG article . Open the geek-init script in an editor of your choice:

vi /jffs/geek/etc/geek-init.sh

If you've followed all the steps in this guide (including the optional ones) you can append the below script snippet to the end of the geek-init file:

logger_general "transmission setup-er: setting 'home'" export HOME= '/tmp/root' logger_general "transmission setup-er: Creating the directory and symbolic-link for the web interface" mkdir -p /tmp/root/. local /share/transmission/ [ ! -L /tmp/root/. local /share/transmission/web/web ] && ln -s /jffs/opt/usr/share/transmission/web/ /tmp/root/. local /share/transmission/web logger_general "activating swap" swapon /mnt/sda_part1/swap.page logger_general "transmission setup-er: Starting the transmission-daemon with the alternate configuration directory." /opt/usr/bin/transmission-daemon -g /mnt/sda_part1/torrents/config logger_general "transmission executed"

However if you've skipped optional steps, while there shouldn't be any problem with leaving the above "code" as is, you may want to take out anything superfluous. In fact, if you've skipped both the optional steps and you forgo the comments, you would only require to append:

/opt/usr/bin/transmission-daemon -g /mnt/sda_part1/torrents/config

Final remarks

• While this may be just FUD , one better keep in mind that BiTorrent has become something of a target for litigation, and that it has been said time and time again, that the network is being scrutinized. Case in point the site   http://www.youhavedownloaded.com/ . Therefore you are advised to only use this torrent client, as we have, for legal torrents.
• During the writing of this article, I have found one torrent that would cause the transmission daemon process to crash due to a memory leak. I have described the issue on the OpenWRT forum , however at the time of this writing, there has been no answer to my hail.

May you have a smooth transition into transmission :)

Because we know it to be transitory, of the moment... we know it will turn to ASH.

From DD-WRT Wiki

When the WRT is used as an Access Point (AP) or repeater (WDS), the WAN port can easily be configured as a normal LAN port.

[ edit ] Adding WAN Port to LAN Switch to use as an additional, normal LAN port

Note: Steps are true for firmwares current as of the author date of this article. v2.4, post SP2 firmwares. These steps were done with build 12307 (2009 06 17). Other firmware builds of DD-WRT have the same or very similar steps.

• Open up the Web Interface to your DD-WRT Device
• Set WAN 'Connection Type' to Disabled.
• Down the Basic Setup page, the option WAN Port appears. Check the box 'Assign WAN Port to Switch'.
• Save/Reboot

The WAN port is now the same as the other LAN ports.

Dd wrt default wan port assignment.

Finally, I set up outbound NAT so this interface could access the Internet. I pressume ping true wireless works because ath0 is assigned to br0 as default while eth0 is indirectly assigned to br0 true vlan1 and does’nt work. Turn off DHCP before you continue! If we go no further, we have a programmable switch that can describe as many as 5 vlans, between which we can do sophisticated routing and filtering.

LAN Uplink Through LAN Port To complete the link between the two routers, connect a LAN port on the central router, to a LAN port on Linksys router to be used as your WAP. DD-WRT Virtual Wifi Network Assign security to this, if you require. Enable this if you want to use WAN port as a switch port Optional NTP Client: You will need to disconnect from the DD-WRT repeater, then reconnect.

But that ignores the wireless part of it , which adds some extra complexity. You can connect the WAP to the main router via LAN-to-WAN so long as you have assigned the WAN port to switch see step 3.

Because its so important, it is worth repeating: All movement or non-movement of packets between the virtual lans is determined by routing logic behind those devices which is normal linux routing , filtering , etc. A few more tips.. Vlan0, [Vlan1] is the one on which all of the numbered RJ45 sockets on the back belong to. I set up a static IP address on the GuestNet interface and also set up DHCP to issue IP addresses. Check our our full selection of DD-WRT pre-installed routers. Be sure to make a backup as mentioned in the following section of the tutorial.

In DD-WRT’s default case, this is vlan0, [vlan1]. In this tutorial, we will create a subnet for each VLAN. Down the Basic Setup page, the option WAN Port appears. What this area does is allow you to create multiple automatic assignment addresses for IP addresses in a network.

Assign WAN Port To LAN Switch

In DD-WRT under Client or AP modes -- where the wired Ethernet WAN port is not used -- the port may be assigned to the LAN switch with a simple GUI checkbox selection of "Assign WAN port to switch."

Can this be done in OpenWRT? If yes, how does one do it?

Yes, you simply need to change the switch configuration accordingly (remove the wan portfrom the wan vlan and adding it untagged to the lan one). Unless you really need the port, I'd usually suggest to ignore it though.

yes change switch connfiguration In AP mode WAN port is required unless you are using radio as uplink

make a network bridge with all the physical ports and name it wan make Lan network withonly wirelss interface in it

check for the relevant changes in firewall.sh done

Thank you slh and arjunet. I want to assign the WAN port to the LAN switch only because it can be done. As an exercise. Is there any reason not to do this?

Can anyone give me detailed directions on what sequence of commands (settings) to use? Moreover, I am completely ignorant of the methods and syntax of the command line mode. Can anyone direct me to a router command line 101?

Yes you can do that ..if it is what you want to achieve

It depends on your hardware. Some hardware has a separate Ethernet port on the CPU that goes directly to the WAN port on the back of the router. In that case you would go to the network configuration, physical settings, and move the WAN ethernet port from the wan network to the lan network.

In other cases, especially gigabit routers, all the ports on the back go through a hardware switch. There you would go to the Network-Switch page and turn off the WAN port in the WAN VLAN, and turn it on (untagged) in the LAN VLAN with the other LAN ports.

DDwrt tries to simplify configuration by giving the user preset "modes" for common use cases. OpenWrt is more toward total flexibility. You can set anything to do anything, even if that is going to totally break it. You can add or edit a file anywhere in the filesystem rather than having only a "nvram" database.

If you're using command line, the most direct approach is to edit the config files. Search the OpenWrt wiki and find the UCI pages. These explain the options possible in each file.

Please understand the question before answering it. OP needs to use the WAN port as a LAN port. They do not need to configure all the ports as WAN. There is a marked difference in the config.

There are two reasons not to do this, unless you really need the fifth port to be usable as an additional LAN port.

• you can get it wrong, soft-bricking the device or creating a number of subtile problems that might haunt you for quite a while
• if the WAN port is a dedicated ethernet interface and not connected to the same hardware switch as the LAN ports, you'd need to bridge it with the switch - this would required the data going through the SOC's CPU for the bridging to work, creating a serious bottleneck in terms of performance

If you are aware of the consequences, the technical implications (dedicated interface vs switch port) and actually need an additional LAN port, there's no reason not to do this - but it shouldn't be done "just 'cause" by a beginner.

dumb AP examples , but read and heed the above.

Thank you for taking the time with the caveats. I'll take my time. Nevertheless I live by the precept "no guts, no glory." After all, how does one move from beginner to experienced without doing what can be done even if it need not be done? This stuff should be not all that hard. I mean, really, how arcane can it be?

A month of serious study and experimentation should be more than enough to graduate beyond the clueless novice level. This isn't rocket science. At least it does not appear to be. I was building DEC PDP11s and LSI-11s linked on fiber-optic serial highways which were in turn connected to CAMAC equipment long before the Internet was a gleam in Al Gore's eye. (My lame attempt at humor, sorry.)

It's not rocket science, but you probably learn a lot by going to the Network > Switch page on LuCi and posting a screenshot, we can tell you how your device is wired up by that.

This is a good beginner project. Log in to the router on wifi so that if you misconfigure the Ethernet you would still be able to connect.

If you do have a separate eth port and thus a software bridge, connect whatever uses the least bandwidth to that port.

@dkwalton hi , please go through the link once

there is nothing wrong if you dont need any WAN concept and making a custum project having only LAN

"Ask and you shall receive." Thank you arjuniet.

YES! That is seriously good advice. Logging n via WiFi so as to maintain a connection. See, I should have thought of that if I knew what I were doing. Bits and pieces make a whole.

dd-wrt: change LAN port to WAN only works without LAN connection

I have a TP-Link 740N v3 router with WAN port and LAN port 1 burned.

I was able to flash DD-WRT and to apparently configure WAN port to LAN port 4 (or 1, I don't actually know how are they numbered by kernel).

Laptop on Wi-fi receives a correct address, from 192.168.1.* network.

But PC, on a wire, receives an IP address from 37.* (for example) network. After that, routing from Internet to Wi-fi 192.168.1.* network stops. When PC is off, Internet appears on 192.168.1.* again. Apparently, PC grabs an external IP and "all the Internel" from WAN.

Is there anything except vlan1ports / vlan0ports I should configure?

Some diagnostics, ipconfig and so: https://gist.github.com/92899e26d2e35897714c

What else do I need to change to get port 4 to be WAN and wired ports 2-3 to be LAN (onto 192.168.1.* network)?

Apparently I need to add another VLAN for local Ethernet ports , other then the "new WAN" (port #4). That's because PC gets an IP over Ethernet directly from WAN, and I need PC to be on LAN (192.*) network.

But my router doesn't have a VLAN admin GUI , though it's of the same version - v24 preSP2 .

I followed all the instructions to separate Ethernet ports into different VLANs , and still no luck, PC still grabs an IP from my ISP as if the router was a simple switch.

• See this link for how to understand port numbers. The entire article has step-by-step procedure of replacing the uplink port. –  Be Brave Be Like Ukraine Sep 25, 2012 at 12:24
• I did follow it, as you can see from nvram show output. Something still went wrong. Do you know what it was? –  Victor Sergienko Sep 25, 2012 at 13:22

Sounds like you haven't configured the LAN ports correctly yet. The ports are still acting like a hub and not like a firewall; hence the PC grabbing the external IP. As far as I know the areas to look into are VLAN(which you're already doing) and global router settings(like if it's a bridge, gateway or router).

Have you tried again with the latest firmware?

• I cannot try the latest firmware - I don't have that router any longer. I believe you're correct about the gateway/router setting. –  Victor Sergienko Aug 4, 2013 at 13:17

How To Configure a DD-WRT VLAN Setup (Router FAQ)

Please note, we are moving away from DD-WRT, as both projects have seen limited development, and do not support the latest features like Wi-Fi 6 and WireGuard. If you’re looking for more information about VLAN or want to see the best VLAN routers, explore our dedicated VLAN page .

If you do still want to use DD-WRT and need assistance with setting up VLAN on your DD-WRT network, we can assist you with our Flash My Router Plan!

Quick Overview

At FlashRouters, our primary goal is to inform users of the benefits of taking back control of their network by unleashing the true power of their router. Routers using DD-WRT Firmware offer a multitude of features, from VPN integration and QoS (Quality of Service) to DNSMasq & Bandwidth Monitoring/Access controls. Another popular feature of DDWRT: VLAN tagging. In this post, we detail how to create a full VLAN setup with DD-WRT.

What is VLAN (Virtual LAN)?

According to Wikipedia , “In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a virtual local area network, virtual LAN or VLAN… More sophisticated devices can mark packets through tagging, so that a single interconnect (trunk) may be used to transport data for multiple VLANs…”

One aspect of a VLAN is the ability to create separate networks on the same router for security and segmentation purposes. Employing a VLAN setup is a useful procedure if you have some devices on your network that you want to isolate from others. In doing so, you can use a VLAN to provide Internet access to family and friends without giving them access to your entire network. Best of all, the settings can easily be changed and adapted to however you want to set up your network.

What Are the Benefits of VLAN?

A VLAN has the same attributes as a physical local area network (LAN) , but it allows for devices to be grouped together more easily even if they are not on the same network switch. Most enterprise-level networks today use virtual LANs.

Without VLAN functionality, you would need separate collections of network cables and equipment from your primary network. And if you didn’t plan this in advance, you could expect a costly rewiring job in your home or office. Unlike physically separate networks, VLANs share bandwidth, so VLAN trunks may require aggregated links and/or quality of service prioritization for maximizing their capability.

For many users, VLAN alone is enough of a reason to switch to third-party alternative firmware like DD-WRT.

How to Create a DDWRT VLAN Setup

Now on to the fun!

In this DD-WRT tutorial, we will set up VLANs for each Ethernet port. This will create a network on each port that is isolated from all the other ports. An Asus RT-AC66U has been used for this tutorial, and while this same interface is pretty constant throughout any popular DD-WRT enhanced router ,  setups may vary depending on your firmware build and router model.

DDWRT VLAN Configuration of Ports 1-4

Go to https://192.168.1.1/ (or your router management IP address) in your web browser.

Select Setup -> VLANs .

Uncheck ports 1, 2, 3, and 4. Place port 1 into VLAN1, port 2 into VLAN2, and port 3 into VLAN3, port 4 into VLAN4. Set the WAN port to VLAN0.

When this is done, the VLAN configuration page should look like this:

Click Save, then Apply Settings.

VLAN Configuration on Each Port

• Next, plug an Ethernet cable into port 1 on the router from your computer.
• Unplug the router power for 30 seconds and then plug it back in. Wait for the lights to return to normal.
• Go to Setup -> Networking.

In this tutorial, we will create a subnet for each VLAN.

VLAN1 will have the subnet 192.168.1.0. VLAN2 will have the subnet 192.168.2.0. VLAN3 will have the subnet 192.168.3.0. VLAN4 will have the subnet 192.168.4.0.

That means devices on VLAN1 will be assigned addresses such as 192.168.1.15 and for VLAN2 192.168.2.50

Under Port Setup set VLAN1 to Unbridged.

Set the IP Address to 192.168.1.1. Set the Subnet Mask to 255.255.255.0

Change VLAN2 to Unbridged.

Set the IP Address to 192.168.2.1. Set the Subnet Mask to 255.255.255.0

Change VLAN3 to Unbridged.

Set the IP Address to 192.168.3.1. Set the Subnet Mask to 255.255.255.0

Change set VLAN4 to Unbridged.

Set the IP Address to 192.168.4.1. Set the Subnet Mask to 255.255.255.0

Save your changes by clicking Save . When the interface responds, the Port Setup section should look like this:

Configure DHCPD

Below the Port Setup area you will see a section titled DHCPD .

What this area does is allow you to create multiple automatic assignment addresses for IP addresses in a network. So, whenever someone authenticates into this section, this VLAN will assign it a user address in your network. This creates 4 sets of automatic assignments within the 4 new segments of your network to be handled by the router automatically in the future.

Under DHCPD click Add . Set DHCP 0 to vlan0 with a Leasetime of 1440 (24 hours). Click Save .

Click Add again. Set DHCP 1 to vlan1 with a Leasetime of 1440 (24 hours). Click Save .

Under DHCPD Click Add . Set DHCP 2 to vlan2 with a Leasetime of 1440 (24 hours). Click Save .

Once again, Set DHCP 3 to vlan3 with a Leasetime of 1440 (24 hours). Click Save .

And a final time, click Add . Set DHCP 4 to vlan4 with a Leasetime of 1440 (24 hours).

Click Save . Let it save. Then, click Apply Settings .

Once completed, the DHCPD -> Multiple DHCP Server section should look like this:

Plug your Ethernet cable into any port on the router aside from port 4 or the WAN port. Unplug the power for 30 seconds and then plug it back in. Wait for the lights to return to normal.

 Adding Firewall Rules to Isolate the VLANs.

Now, we have created 4 network segments, but we need to use a firewall to fully isolate them from each other. These commands block all VLANs from communication with each other.

Browse to Administration -> Commands.

Copy and paste the following commands into the Commands text box:

iptables -I  FORWARD -s 192.168.1.0/255.255.255.0 -j DROP iptables -I  FORWARD -s 192.168.2.0/255.255.255.0 -j DROP iptables -I  FORWARD -s 192.168.3.0/255.255.255.0 -j DROP iptables -I  FORWARD -s 192.168.4.0/255.255.255.0 -j DROP

Click “Save Firewall”.

Your DD-WRT VLAN basic configuration is now complete.

Testing the DDWRT VLAN Setup

To test each VLAN, connect to that port. Take note of your IP address and see if your local IP address changes in your network. If it changes, you have correctly set up VLANs, great job!
