    The main request is to setup a GRE tunnel between a Cisco and A Sophos Device and IPSec over it. I give support for the Sophos End and when the configuration was completed I was able to ping the Cisco Tunnel IP but the other end (cisco) could not ping my own tunnel IP.

    This is the reason why i decided to setup a LAB and create GRE tunnel between two sophos device and its obvious now that the issue i was facing with the Cisco device is occurring as i cant ping the two XG remote tunnel IP from the host.

    And Pcap share above shows that the traffic is going out but not been received. I have created several Firewall rule and routes it's still not working.

    So forget route based VPN the request is a GRE tunnel.
