VPN Drops after phase 2 establishment

Hi,

I have a Site to Site VPN between ASA and ForeFront TMG. I am able to establish the tunnel. However, the moment pahse 2 is established, the very next second tunnel is dropped.

On ASA, I get to see... received delte SA message

And on ForeFront Iget to see the below message:

tunnel model in two NAT setting is not supported.

Both the VPN peers are behind a NAT device.

Please help.

VPN Drops after phase 2 establishment

Hello,

I think you need to configure Nat traversal on the ForeFront TMG side.
