Hi, I am attempting to build a Linux firewall/router. I have managed to install slackware and get everyones machines talking to each other, no problems there. I have got NAT working by using the following command in iptables.
Code:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
I want to have a deny all policy and then specify what i want to enter the network. This is where i get confused. Do i perform the filtering within the INPUT chain of the filter table. Just a pointer in the right direction would be nice.
Thanks
