Need a basic IPTables script for multihomed Linux box with simple packet filter
Posted on 2008-10-22
I need to configure a simple firewall on a Centos 5 Linux box using IPTables.
The box is multihomed with eth0 being LAN and eth1 being WAN.
All I want to block is all inbound traffic on the WAN apart from UDP Port 4569 (IAX2 protocol).
Not using NAT or routing, no problem with all outbound WAN traffic being allowed either.
