2 interfaces with Nat Outside

[FlorinP]

Hello all,

New to cisco, studying to get my CCNA R&S diploma, and I am facing an issue, that I cannot seem to get it done.

I have created an intervlan routing in the right of the example and static routes to the left of the example. 

I have implemented NAT that is working on R0, but if I try to implement NAT on R2 , using inside on Gig0/0 and outside on Gig0/1 , everything falls apart . I may not understand why using nat on 2 different interfaces in the network is not working. 

With only one everything works as you can see, but if I implement a new nat on R2 everything falls.

Can someone help me out with a small explanation and maybe a point out to some documentation ?

Thanks.

Can right side ping 4.0.0.0/30 network?

Maybe the translation from 5.0.0.0 to 4.0.0.0 on R2 cause this issue, check if the right side have a route to 4.0.0.0 network.

Regards,
Fernando
