2 Routers, 2 ISPs, Connect?

[HoloZapz]

Is it possible to connect 2 routers that have SEPARATE ISPs?

I have a buffalo WHR-HP-G54 with dd-wrt on it and is hooked up to dsl. My brother has a linksys WRT54GL with the factory firmware and he is connected through cable.

Would it be possible to have the routers connect and still use our own respective isps? Or would we need to set one as a client and just leech off one or the other for our internet needs?

Any help is appreciated!

Yes, you can connect multiple routers to the same private LAN.

What are you trying to achieve by doing so. Load balancing? Fault Tolerance?

There are few ways to go about it.

The choice depends on what you intend to two with the connection.

The one thing that you can Not do is creating one cohesive Internet connection that combines the two Bandwidth together.

Well, my brother loves to have lots of bandwidth and didn't find it cool to share a 3mbps down with everyone. So he got his own isp and enjoys it all for himself.

We just wanna connect to a common network to file share. So he would be still using his own connection and I would still be using my own, but we would have access to each other's computers.

Hook up your network like this:

 [FONT=Fixedsys]|     WAN    |
 |            |
 |            |
 |            |
RTR1        RTR2
 |\          /|
 | \________/ |
 |            |
 |  INTERNAL  |
YOU          BRO[/FONT]

Turn off DHCP on RTR2, and make sure the router's internal addresses are on the same network. For example, if RTR1's IP is 192.168.0.1, make RTR2's IP 192.168.0.2.

Give your brother's PC a static IP address on the same network, and make sure that it's default gateway is set to the IP of RTR2.

Edit: If you want to add fault tolerance to this configuration, set static IPs on both PCs. On your PC, set the first gateway to RTR1, and the second gateway to RTR2. Do the reverse on your brother's PC.

Ah, I'll try that when I get home after work. Thanks for the help!
