Cannot Reach LAN after NAT outside and NAT inside.

Jonathan Nali
Level 1
Level 1

Hello everyone,

I just finished my MPLS configuration but I have one last roadblock. 

I can reach my HQ LAN(10.10.1.0/24) from my branch but HQ cannot reach branch LAN(10.10.3.0/24).

This happened after I did NAT outside and NAT inside on the branch router. 

I can reach the interface facing outside but cannot reach the interface facing the LAN

Hi @Leo Laohoo ,

thanks for the suggestion. 

Fortunately, it's real life, the image is just a network map.
@Georg Pauwen , it is not a packet tracer project. I just used PT to draw my network map. the issue is on the router configurations.

Hello,

 

post the zipped Packet Tracer project (.pkt) file...

Hi, 

Do you have a solution in mind?
