SITE TO SITE VPN CONFIGURATION WITH OVERLAPPING SUBNETS

Hello

 

I am configuring a Site to Site VPN with another client.

 

The problem is the networks are overlapping and such we have decided to NAT. However the VPN tunnel is not coming up.

My actual inside private ip address is 10.10.10.20 and the NATTED ip address is 192.168.10.100.

what could I be doing wrong or is my NATTING or ACL not right. Partial config attached. addresses are not real

 

thanks

After seeing the first syntactical problem in the first line through your editing, I didn't look any further. Just some advice from personal experiences:

  1. The needed double NAT is a PITA. They cause confusion the whole time where they are in place.
  2. Also think about renumbering the smaller or the "easier" site.
  3. What about an overlay IPv6 network only for the systems that need to communicate?

I managed to resolve this.

 

Thanks Karsten

Can you tell us how you fixed this ^

 

I am having the same issue. The VPN comes up but I cannot ping the remote ip address
