Hi list, I have a lan with 32 PCs and a Redhat 7.3 (192.168.1.1) running IPTABLES to route the lan into the internet. I am using a ASDL dymanic internet service and RP-PPPOE. I would like to block the network from connecting to MSN and AIM. At the same time, allow every machine to access to the mail server outside of the lan. Most of these machines will not have access to surf the internet. For example, 192.168.1.2 - 192.168.1.10 will have full access out of the lan into the internet. 192.168.1.11 - 192.168.1.32 has only access to the mail server. Has anyone got a working script, a faq or even tutorial which i can read up on? Thanks and regards
