I am trying to configure a simple firewall. I want to have the firewall use NAT to translate the internal address to public. This will need to happen in both directions. All servers will reside behind the firewall. I will create holes in the firewall to allow traffic to each port. Simple huh!!!
Well I've been trying for 2 weeks and need a lot of help. Can someone send me a sample. I am using Slackware 8.1 kerneral 2.4.19. and IPtables 1.2.6a
My internal interface is: 220.127.116.11/24
My external interface is: 18.104.22.168/24
All servers will be 22.214.171.124 - 126.96.36.199/24
Web Server will be located at 188.8.131.52/24
I would like to block everything inbound else port 80, 110, 25 etc.
