Hi,
I have set a new tunnel on a Cisco C1800 router to one of our clients and it turns out that we have the same internet provider and they are using a public IP for their internal NAT. Phase 1 goes with no problem but when they initiate traffic I receive it through the VPN tunnel but the return goes to the public internet and get lost following our provider´s routes.
I need to force the traffic back to the tunnel. Here is part of the configuration and the crypto IPSec result. My public IP is a /30
Best regards end thank you.
FYI: The asteriscs mean that they have the same octate. Hope makes sense.
