networking two routers with different ISPs

[peteykaw]

I have two home networks running, one on a wired 4 port router with phoneline ADSL internet and a second on a wireless 4 port router with cable internet. Any help on how to join the two for file sharing and other LAN access without using the internet to accomplish it would be appreciated. In all of my searching, no one has had two different ISPs on the routers and I'm not sure if they will interfere with each other or not. Access to either ISP from each comp would be a bonus, but not essential. Thanks for any ideas.

Easiest way is to use a DUAL homed router. It has 2 WAN connections. It looks like a singele NAT/router and has DHCP for one gateway. But the router will send the request over either WAN port. Several companies make these at a reasonable price.

The ISPs should not matter. You need a LAN interface and a public interface.

You could try linking the two routers using a cross over ethernet cable, but first check that all the IP addresses are unique on all devices and if you are running DHCP on both routers you may need to turn one of them off. Some routers will pick up if a cross over cable is used or not. Then as long as the two networks use the same IP range they should all talk. To choose which internet connection to use you will need to change the proxy settings in your applications. You may need to fiddle with adding in the DNS IPs into the network connection settings etc.

What OS on all clients?

Why DSL and cable.....could just connect everything to cable.

XP Home SP2 on both cable clients , XP Home SP2 and ME on the 2 DSL clients.

Using the Cable for gaming server, Teamspeak servers and FTP (IP is static for the most part). DSL for all other internet apps as IP rolls intermitently but frequently.

I spent a couple of nights playing around with all the suggestions here and in several other posts and finally just left them independent and use a VPN connection between the two main clients when I need to network. Its not what I would have liked but it functions and thats what matters most. Thanks for your suggestions though. This site is most informative. petey
