Thanks for the response but it didn't work. It just hangs there trying to connect and then I get an error "no route to host" (as it should if trying to connect to that host directly.

Hi,
Try this:
iptables -t nat -A PREROUTING -p tcp -d old_mailserver_ip --destination-port 25 -j DNAT --to-destination 127.0.0.1:25

Hi,
I am trying to set up a firewall rule so calls to old_mailserver:25
get
redirected to localhost:25. I have seen quite a few rules and none
seem
to work.
I have tried with the firewall enabled (configured to allow smtp)
and
disabled, but it doesn't seem to make a difference.
One of the commands I have been using is: /sbin/iptables -t nat -I PREROUTING -p tcp -d old_mailserver_ip/32 --dport 25 -j REDIRECT --to 127.0.0.1:25
Am I missing anything?
Thanks
Gabriel
