How translate Multiple Global IP Addresses to Single Local IP router 831

josedunet · ‎08-13-2009

Hello All,

I have an smtp server at 10.10.10.3, located behind my cisco router 831 whose inside global ip is for example 81.81.81.1.

the server needs to be accessible to the outside network interface by its internal IP address of 10.10.10.3. I want to do a port redirection.

How i can do it?

You can do it using static nat.

ip nat inside source static 10.10.10.3 81.81.81.1

configure ip nat inside on your lan interface and ip nat outside on your internet facing interface.

Hope this works
