GRE tunnel and static NAT

Unanswered Question
Nov 11th, 2009

I'm trying to setup a GRE tunnel between 2 routers either side of a PIX515E. Tunnel works fine when no NAT is configured but when I add NAT the tunnel won't re-establish.

I have changed the outside router's tunnel destination to the NAT address on the outside of the fireall and added a route to that address via the physcial interface address.

Firewall rule has been set up to NAT from outside address to inside router's Loopback address(tunnel destination)

I have this problem too.

thanks, I'm doing the NAT on the PIX. This works OK when using other services such as telnet but not with GRE
