Hello all,
I am trying to setup a Cisco GRE tunnel between 2 Cisco routers, one of which sits behind an ASL 5.2 box. I have setup NAT rules to map an IP on the outside of the ASL box to the internal IP of the Cisco router. I have also setup packet filter rules to allow GRE traffice in and out of the firewall, but I can't get the tunnel to work. Has anyone successfully done this? Any help is greatly appreciated.
Dave
