NAT - Connectivity between equipment in different private networks

[vargas17]

I'm trying to establish connectivity between the devices in the private network of cluster0 and those in cluster1, and vice versa. I've configured dynamic NAT on the border routers of each cluster. The private devices in both clusters can ping external destinations (ISPs) without any issues. However, when I ping from a machine in cluster0 to one in cluster1, it fails. I can see NAT translations occurring in the border routers, but the ping never reaches its destination. When I use traceroute, it shows that the packet doesn't go beyond the public IP of the corresponding border router. I would greatly appreciate any help or ideas on this matter. Thank you.

Attached is the PKT file of my scenario.

Hola,

Creo que esto es un defecto de Packet Tracer. Lo he visto muchas veces: si configuras NAT en ambos lados, parece que no funciona. Si desactiva NAT en un lado, hay conectividad.

I understand, I have done that and it has worked just as you say, thank you very much for the clarification!
I have some doubts, sorry for that. This behavior in real life should not be like this, i.e. having nat on edge routers of two organizations that are connected should work without any problem?
