iptables , squid and mail

kcpant — Fri, 28 Jan 2005 07:18:01 GMT

Hi friends,

new question: I've setup a RH 9.0 box with SQUID, iptables. first problem is, even after setting redirection to squid's port ( I use 8080) in iptables, enabling packet-forwarding, and setting squid in accelerator mode, transparent proxy not working. I've made transparent proxies on RH 8.0 2-3 times , without any problem.
second problem: can I forward mail client packets directly using NAT policies? if so, which ports to be NATted? I want that my clients should use web through SQUID, but can access mails directly( all clients are M$ based). NATing 25 & 110 ports only does not seems to work.I believe some other ports also have to be SNATed.

Witing for ur reply

Thanks

The best place to handle mail is with iptables.

Iptables has a simple configuration for handling NAT and port forwarding.
