I'm having a little problem getting my head around routing in Linux
OS: Centos 5.3
Have have two NIC's install in this server
NIC1 is drectly connected to the internet in a datacentre via a switch and has a public IP. It needs to route its traffic via another public IP(gateway)
NIC1 has IPtables enabled as a firewall
NIC2 has assigned a local IP address.
Problem: I cannot for the life of me get internet access. I'm used to using a Cisco router/Pix for this type of thing, but because of the shear scale of traffic, the Pix I normally use, cannot cope.
Can someone give me some pointer?
