Hi All

I have two sites A & B connected as below:

A(4507 switch) <-------------> B (2970 switch) <-----> B (2811 router)

Gig port of 4507 switch of Site A is connected to 2970 switch of site B. 2970 switch of site B is connected to 2811 router at same site.

I have created a sub-interface on router. I have assigned /30 IP address on 4507 and on router su-interface. The connectivity is running fine. I am able to ping router from switch and vice versa.

Now, I want to do NAT between sites. The IP pool at site A:, Pool at B:, Pool for NAT:

At site A: I have defined a route for towards site B router.

At site B: I have defined a route for towards site A switch. Also I have done a static nat of to But I am not able to ping from site A.

My question is, as the sub-interface of the router have incoming and outgoing traffic; what shall I define on it "ip nat inside" or "ip nat outside" or if I am doing something wrong ?
