Deleting NAT statements.

If you are talking about DYNAMIC NAT translations, then you can clear them with "clear ip nat trans *" command. If you want to remove any STATIC NAT (one-to-one translation), then you should remove the line from the configuration (conf t, no ip nat...), and then issue the "clear ip nat trans

Good luck,

After you remove the NAT statement you need to clear the NAT translation table. "clear ip nat trans *"

I apologize. All the NAT translation are static and there is no way to have the statements deleted even if I apply "no ip nat inside source ....." at the "conf term" prompt.

I need a lot of luck........ :-(

Thanks Alex

You can absolutely remove them. If it tells you that it cannot be removed because they are in use then you need to clear the nat able first, remove the nat statement then it's always a good practice to clear the nat table again.

The problem was that the router accepted silently the negation of the NAT statement but didn't remove the statement at all.

Anyway I rebooted the router, after having deleted the "ip nat outside/inside" from th einvolved interface and now it works fine.

Thanks to all.

Let me point out that when I enter the command "ip nat inside source static ..." the router diplaye a newline so that I got the prompt string not just the line underneath but that after with a newline in the middle. Don't ask me why.
