Hi all,

I have tried to figure out how to do this one but I think I have just confused myself more…
My firewall is a 2 interface setup, the same box is my router to my uplink.

I’m not using nat at all and have a public IP range behind this machine.

net = eth0

loc = eth1

Most of my rules are mainly the basic

HTTP(ACCEPT) net loc:

SMTP(ACCEPT) net loc:

This time around though I wish to just redirect (or is it translate) a port but because I’m not using nat etc I’m not sure if this is possible.

I have a mail server behind my firewall that already has a rule in place
SMTP(ACCEPT) net         loc:111.1111.111.111

So this allows inbound port 25 connections to the machine on loc no issues at all.

What I want to do is have an incoming connection on port 26 to BUT redirect it to but on port 25, is this possible?
