2 complete networks  on one centos box

This is my third question to try to solve my issues, hope this one is clear and accurate.

I have 2 complete networks on my centos 5 box.

EX:

eth0 (192.168.1.0/24) -> ROUTER (192.168.1.1) -> INTERNET (PUBLIC IP)

eth1 (10.0.0.1/24) -> ROUTER (10.0.0.1) -> INTERNET (PUBLIC IP)


What I want is anything coming in on eth0 goes out on eth0 and the same for eth1.

I dont care if its static routes, iptables or whatever... I just want whatever coming in on eth0 goes out on eth0 and whatever comes in on eth1 goes out on eth1.

reason:
I have ssh/sftp users coming in on eth0 (192.168.1.2) and they need to go out that same link (higher speed connection)

I have internal people using eth1 (10.0.0.2) as their proxy server, and they need to go out on eth0 (so when people are downloading/uploading on eth1 internet is not slow for LAN users.

ANY HELP IS APPRECIATED!

CentOS (and Linux for that matter) won't be able to do this by conventional means as for what you are asking for is considered a static NAT translation and routing table nightmare. Your best bet will be to look at using Shorewall Firewall/Router and deploying its Multiple Internet Connection Support.

I have not set up such a routing layout, so this is where my help ends on this type of configuration.

This alternative configuration might work in a limited fashion.
