Hi guys, Im not the most advanced user but just wondering how I would do a port address translation to point to a specific server on my network. For example, I have my mail server on my internal network and I want to pass all traffic coming in with port 25 as the destination port to go to my mail server. Thanks in advance.

This should be in route forum but anyway...this is a template for PAT:
interface f0/0
description WAN LINK - NAT OUTSIDE
ip address 1.1.1.1 255.255.255.0
ip nat outside
!
interface f0/1
description LAN - NAT INSIDE
ip address 2.2.2.2 255.255.255.0
ip nat inside
!
ip nat inside source static tcp 2.2.2.100 25 1.1.1.1 25 extendable
!
This configuration maps the inside IP address 2.2.2.100 and tcp port 25 to outside IP address 1.1.1.1 tcp port 25. I assume you know a little about the NAT configuration so I skipped some common commands.
