Hi There,
I am trying to statically NAT my email server on 2 different internet connections on my border router but this is failing as soon as enter the second static NAT command and it gives me an error message stating that the address is already NATed! Is there a way to NAT the same IP on 2 different global address?
The configuration I am using is:
ip nat inside source static 192.168.10.4 x.x.x.x
ip nat inside source static 192.168.10.4 y.y.y.y

Hi Haitham
You need to use the extendable keyword at the end of your NAT statements.
Here is a link to a NAT overview doc. Scroll down to the "Feature Enhancements" section. There is an example for what your trying to do.

hi,
you can go for like this...
ip nat inside source static tcp 192.168.10.4 25 x.x.x.x 25 extendable
ip nat inside source static tcp 192.168.10.4 25 y.y.y.y 25 extendable
