I have a RH7.1 server connected to the inet.
I have squid installed and my workstations can browse the net. No problems.
What I would like to do is allow all the stations to use (for example) FTP, ICQ, NEWS, and so on.
The system is enabled to use IPCHAINS, but not yet configured.
I also need to block the clients from accessing private mail (Block ports 25 & 110 to a certain ip address c.c.c.c on the internet)
My system is like this
eth0 a.a.a.a connected to the internet
eth1 b.b.b.b connected to private side
