NIC Bonding with Dynamic IP

[okeofs]

Greetings all!

I'm trying to set up a bonding scheme for a server that we're running in our house to provide internet for 16 guys. We have 4 NICs in the box as follows:

eth1
eth2
eth3
eth4

eth1 and eth2 are each plugged into a cable modem that gives each interface a dynamic IP address (Cox). eth3 and eth4 each feed the WAN port on a linksys wireless router running dd-wrt. What I'd like to do is bond eth1 and eth2 so that we have load balancing and redundancy, and eth3/eth4 will handle dhcp to all the clients downstream of them through the routers. In short the gentoo box will be running a dhcp server and the routers themselves will just dhcp forward to all the clients that connect to them.

I've tried following the gentoo wiki guide for bonding, but I'm unclear as to how the dynamic IPs for eth1/eth2 affect the bond. I'm able to get the bond up but I can't get any traffic to pass through. I'd be happy to post any reports or information needed.

Thus I hope to end up with the following:

Cable Modem -> eth1 \.................................... /eth3 -> Router -> Computers
................................> bond0 -> DHCP server >
Cable Modem -> eth2 /.....................................\eth4 -> Router -> Computers

Best,

Jon.
