Hi everyone,
Can anybody help me how to configure iptable for pop3 and smtp
I have setup a gateway server FC9, the network details are as follows :
LAN (172.16.251.0/255.255.255.0 ) ---> Linux server (fedora 9, eth1 172.16.251.234, eth2 172.16.250.246, gw 172.16.250.245) <--router (172.16.250.245)---> internet
On gateway server (FC9), I am using squid 3 Stable 13 for HTTP proxying using NCSA authentication.
Now my LAN clients (all are having static IPs) want to access mails through outlook express.
Please, advice me, how to set iptables chains on linux machine. I don't want to use MASQUERAD other wise user would be able to access Internet directly and squid would be of no use.
Can anyone provide me a simple solution.
Thank you very much and regards.

The Fedora list isn't really the place to ask this question. Netfilter lists would be more appropiate.
A simple solution would be to just forward connections to the few ports that you want to allow and block the rest (that would require forwarding).
