I have a cisco 1720 router and need to map a public ip to a local ip. Can some one please help me. Trying to set internal email and post a webpage.

Hey michelle:
Cisco's nat is counterintuitive and I am not familiar with your router series.
I would check out the cisco site for some
examples.
Tou will need nat to masquerade your internal
(private) ip.

Good Luck.

What you're after is called "Policy Routing" and is actually quite easy to configure, once you understand it.

You'll have to create an access-list defining what protocol goes to which IP, and then apply it to the external interface.

I haven't done this in almost two years, so my memory is a bit foggy as the exactly hwo to do it. If you search on masquerading, though, you won't find it. Use policy routing.

Good luck,
Chase
