I have both dsl and cable internet. I'm trying to make everything work together on my linux box. The setup is as follows

eth0 - cable
eth1 - dsl
eth2 - internal network

I have all internal traffic being masqueraded over eth0 (cable) fine. I'm having trouble getting the dsl connection working. Getting an IP is no problem, but I am unable to ping or any other network traffic using the dsl interface. I'm thinking it's a routing issue. If I add a default route with a metric of 1 that points to the dsl providers GW, I can ping using both interfaces, but still can't accept traffic on eth1.

Let me know if this makes any sense, and thanks for any help.

Hmm... That's a *very* interesting question. Let me get this straight... You are using this box as a router, right? eth0 is forwarding all 'net traffic from your LAN.

It definitely seems like a routing issue. Unfortunately, I'm not too sure how to solve it.

I would suggest looking into Squid. It's considered to be a very powerful caching/proxy server. You can find it at Squid Homepage (http://www.squid-cache.org)
There is a Configuration Guide on the page, and it should help you configure it.

Maybe you could use it to redirect all of your LAN traffic using Squid to your cable interface. Then, you might be able to set up your DSL interface as the box's default interface.

Now, what should happen is your machine will use the DSL interface, and all LAN traffic will be routed through the cable modem. Now, this is just conjecture, though. I would read through the Squid documentation to see what could be done. Hope this little bit helps!

With 2 different isp, it should work. I don't see any benefit if you have one isp with a range of ips, all use the same gateway...
