Hi,

I have four ports for the network on my server, but only two are working...

You probably want to use a netmask of 255.255.255.0 for your subnets (eth1 - eth3).

And look at your routes. The ouput of the netstat command may be due to the netmask used. It should look like:

Code:

192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
192.168.3.0 0.0.0.0 255.255.255.0 U 0 0 0 eth3

We'd have to see his router config to know for sure. I mean, he could just be using 192.168.# for organizational purposes.

I think it would be nice to know which of the two are working, because I see TX and RX for 3/4
