WIFI networking: two routers on the same network
January 13, 2013 5:45 AM Subscribe
I am trying to set up a surplus router as a NAS and torrent appliance, to integrate into an existing network. The setup will use two routers, one to provide network and internet to everyone, the other will use TomatoUSB and will be dedicated to torrenting.

Existing setup: A Netcomm all-in-one router which does VOIP, modem, WIFI, routing etc currently does all networking for the house. The household has three Windows PCs, three iPads, two smart phones, one network printer/scanner/fax. The most network intensive thing it ever does is torrent downloads, but VOIP call quality can be an issue sometimes.
I have an ASUS RT-N16 router, which I have flashed to TomatoUSB, which includes built in support for Transmission torrent software. I wish to use this as a dedicated torrent downloading machine, integrated with my existing network.
Flashing TomatoUSB on was fine once I found a compatible build, I installed Transmission QT on my PC and that's working fine too. Everything works.
But it's not set up properly. To get my computer to talk to the Tomato router I need to log in to the Tomato router's WIFI network. When I'm logged in to that WIFI network I can set up the torrents, but I'm disconnected from the rest of the network and can't print. Therefore I've got this awkward arrangement where I have to switch between WIFI networks depending on what I want to do.
Why? Because I can't figure out how to get it working the other way!
So this is less a question about TomatoUSB, more a basic question about network and WIFI setup, router configuration etc.
Currently the Tomato router is wired via its WAN port to one of the LAN ports of the Netcomm router. The Tomato router refuses to let me set it's network IP and subnet ranges the same as the WAN, hence I have two networks that don't talk to each other.
I do not require the Tomato router to do anything wirelessly, I'm happy enough to turn off its WIFI signal and have it communicate only with the network with ethernet cables.
I've heard about "bridging" routers, but admit I'm not knowledgable enough to know how to use it properly. My attempts to muck about with it and figure it out resulted more than once in being locked out of the configuration screen and having to factory reset, so maybe I need expert help!
Of course I have Googled the issue, but everything I have found so far describes setups different to what I want, like bridging Internet to the Tomato router and having it handle the whole network, or using the second router to extend WIFI range.
Also, I want to be able to quickly kill torrents if I have to, so although I could configure it so the Netcomm router bridges its internet connection to the Tomato router which then would handle all the WIFI, this is not the option I would like to go with. I wish for the Netcomm router to continue to handle everything it currently handles, which it does perfectly well, and for the Tomato router to simply join that network and be able to be switched off any time I so wish. Also, the Netcomm is doing a great job where it is, I am not worried about needing to increase the wireless range or anything like that.
Briefly, my questions are as follows:
Do I need two cables, one to the WAN and one to the LAN, or can I set it up so that a single ethernet cable (to either the LAN or WAN ports of the Tomato router) would join the Tomato router to the network? I assume it's possible to use one... how?
I also suspect I should be turning off DHCP and NAT from the Tomato. How do I do that without getting locked out of the device? Both previous times I've played with that I've had to reset to factory settings to get back in.
What LAN and WAN settings on the Tomato router would tell it just to passively join the other network and not try to form its own one?
