Hey All,
I was wondering if it is possible to make a nat address to just one certain ip if possible ? I am a newbie to cisco but my question is this. for example my public ip for my mail server is, and i want this to point to ? is this possible ? i am just learning cisco and was wondering how this would be possible with out bothering other nat address`s that would be used for web surfing. I am using a Cisco As5300 IOS is 12.0
         Thanks !

You can do a static NAT. It is in the documentation for IP. I will post the URL as soon as I can reach their web site. It seems to be down right now.

Hi Jgarr,
Would the command be this ???
ip nat source static

if so then it would be great, cisco is a great site for info but not enough info to know about general info for easier reading.

Hi Peterh1975

Yes, you are right.
Apply the nat to Internal Interface (eg: ip nat inside)
and to the outside interface (eg: ip nat outside)
thats all it will work. hope u hv done separate group natting for browsing.

Good Luck

You could actually do both static and dynamic at the same time if you wish. Here is the document explaining it.
