Basic firewalling

Basic firewalling

[Santhosh, H.]

Hi
Please help me with the below setup

External pc1<-------->(eth1)Server(eth0)<------>Internal pc1

1. What is the cmd to route data from internal pc1 to external pc1 through
the server using iptables or route cmd
2. What should be the gateway value in Internal & external pc
3. How do I make the iptables make it permanent so that after reboot also
those rules should remain

Thanks in advance



		Regards
