Two cable modems...

[Jason Deraleau]

Ok, here's what I'm trying to do. I have a Debian box running kernel 2.2.19 with 3 NICs in it. All the NICs have drivers installed and work properly. I am trying to hook up two different cable modems to eth1 and eth2. Both modems are using DHCP to get their IP address, which is also working properly. They get different IP addresses on different networks (24.241.62.0 and 24.241.140.0) with different gateways. When I have just eth1 up, I can browse just fine, no issues. If I use just eth2, same thing, no problems. When I try to use both at once, only the second interface initialized will work. If I go to another box on the net, and try to ping the interfaces, only the latter one works, the other doesn't respond. The goal is to get both modems responding so that I can use the upstream of each modem. Anyone have any ideas?

Thanks

Only one default route can exist on any box. Therefore only one interface can be a default route at any one time. You have to use static routing to handle traffic on the second interface. That makes the second one only useful for routing between known hosts (setting up vpns between known hosts).

If there are some more advanced tools out there to pull this off id love to hear about them.
