Cisco Port Translation – IP NAT inside

by danerdo . Updated 25 years, 2 months ago

I am attempting to run multiple TCP/UDP ports through my router connected to the internet.

I need to pass ports 25, 500, and 1723 through it. I am not able to use the ip nat inside source static tcp xxx.xxx.xxx.xxx 25 xxx.xxx.xxx.xxx 25 format for separate ports together.

The only way I can get any traffic to pass to a particular private ip is to literally do the entire IP from the public side to my private side with no ports designated.

This leaves me with only one translation allowed.

Does anyone have any suggestions. I am trying to setup www, firewall, vpn and smtp.

Thanks.
