Hello!

I want to have two nat overload

Gi 0/0 is internal interface with nat inside
Gi 0/0.5 is external with nat outside

There is rule:

ip nat inside source list 2 interface GigabitEthernet0/0.5 overload

If I try
ip nat inside source list 2 interface GigabitEthernet0/0.8 overload

I get

%Dynamic mapping in use, cannot change

If I add
ip nat inside source list 3 interface GigabitEthernet0/0.8 overload

and add ip nat outside on Gi 0/0.8
then there is no translations in
sh ip nat translations

Is it possible to solve this problem?

Hi there

Maybe you should use route-maps instead of access-lists.
Then it is possible to have several outside interfaces.
