Simple Port Forwarding

[trippk]

I have a 506e and I would like to forward all SMTP and POP3 traffic to our Exchange server. The IP Address of the unit is 192.168.1.1. Can someone explain to me how to set up a port forward for this unit.

Thanks in advance,

Tripp K.

Hi,

if the outside interface of the pix has a fixed address, then use these commands:

static (inside,outside) tcp 25 192.168.1.1 25 netmask 255.255.255.255

access-list inbound_smtp permit tcp any eq 25

access-group inbound_smtp in interface outside

If the outside interface of the pix has a dynamic address, then you will have to upgrade to version 6.3.1 and use these commands:

static (inside,outside) tcp interface 25 192.168.1.1 25 netmask 255.255.255.255

access-list inbound_smtp permit tcp any interface inside eq 25

access-group inbound_smtp in interface outside

Good luck!!

Kind Regards,

Tom
