TomatoUSB

I have to Internet connections in my house, both have a tomato-usb router. They work fine separately, but if I want to access a device on the other network then I have to switch my wireless connection to the other network. I want to setup a route between the two networks locally via a wired connection. I have seen tutorials on doing this via VPN, but I don't want to go across the Internet, as that will be slow.

I tried plugging in a network cable between 1 port on the router and the same port on the 2nd router. Then I setup a route in each router.

router 1: 192.168.52.0 192.168.52.1 Interface LAN 1
router 2: 192.168.51.0 192.168.51.1 Interface LAN 1

The idea being if I try to access anything in the IP range of the other router it should pass it via that separate connection.

Of course it didn't work and it got me thinking, is this even possible? Somehow I have to setup one of the ports differently than normal.

I can see that this could be done with the use of a third router fairly easily to bridge the two networks, but I can't get my head round how to configure this with what I have.

Can anyone help point me in the right direction as to what I need to do.

I can see two easy ways to do it. Method one is to enable remote admin access on the routers so that you can log into them over the internet via their WAN.

Method two ( which is what I would do ) is to put the LAN of both routers in the same subnet. Router #1 can have LAN IP 192.168.52.1 and router #2 can have LAN IP 192.168.52.2, and then connect LAN to LAN with a cable. With this setup the devices on either network can select which ever internet you want them to use by selecting the approriate gateway IP address of 192.168.52.1 or 192.168.52.2
I am guessing that you already are not using DHCP to hand out addresses, which would be good.

I don't understand how enabling remote admin access will help?

My problem is I can't just connect a cable from one to the other and use that as the gateway to each other network. Somehow I need to configure tomato to tell it that these certain LAN ports are to be used for the gateway to the other network.

Actually thinking about it, is it maybe just that I should be using a cross over cable?

Why not use combination of wireless and wired? Just remove other DNS server.

I don't understand how that relates to my issue, how will that bridge two different networks? I want to keep both Internet connections, and I want to be able to access the devices on each network from each other.

If you want to keep both router connected to internet, there is no solution to do that over LAN if you don't connect with LAN => LAN cable.
I shoul'd done it with openvpn link over internet, probably best solution.

Just me to cent's

Sorry, I did not read your original request very carefully. I thought you were just trying to access the "other router", but you want to access devices on the other LAN.

I don't think static routes will help you since you cannot route on the LAN connection. That would require EBtables which is not included with Tomato. Static routes work if you are routing between LAN and WAN.

Method #2 as I posted above would accomplish the goal.
