I am attempting to setup a basic PAT configuration on a 871. Is it possible to do this on a router that has a dynamic external IP address? Can anyone give me some feedback on how to make a PAT entry to send a specific port to an internal host?

Basically, there is not much too it:

int fa0

ip nat inside


int fa1

ip nat outside


ip nat inside source static tcp 10.1.1.1 80 80 extendable


The only catch is that you need to reconfigure the router when the dynamic ip changes.

So there is no way to set this up one time and not have to re-configure the nat statement everytime the dynamic IP changes?
