how to configure a linux box as a firewall using iptables

Deuce · #1 (**permalink**) 11-06-2001

I have already compiled the kernel and configured it to run as a firewall. My computer has 2 NICs and is on two seperate networks. I can ping both networks from my computer, but workstations on one network can not ping workstations on the other.

What Scripts or commands do I need to install ?

Consider using a 2.4 kernal so that you can take advantage of iptables which is easier and more powerful. You can do a lot of things in iptable much more simply than ipchains, and since it is session based (unlike ipchains which is sessionless) it can detect some attacks much better than ipchains.
