It's doable on 2.4.x with DNAT as far i know eg.
iptables -t nat -A PREROUTING -p tcp -d your_old_mail_server_ip \
--dport 25 -j DNAT --to your_new_mailserver_ip:25so upgrading to 2.4.x would be my suggestion. -- Sebastian Bruhn Air2.Net System Tekniker / System Technichian Email: [EMAIL PROTECTED] Today is Setting Orange, the 45th day of Chaos in the YOLD 3168
