So My Router has static IP 41.33.x.x  as a wan Internet and installs another interface specially directly to Sophos with IP point to point 172.30.30.0/30

they install a VPN on the router on H.Q  and installed a Local loop on a branch

 So .when tracert to the branch From H.Q is success reachable

when tracert from branch to H.Q is stuck on the interface from Side my Sophos 172.30.30.2/30

i make as bellow

1- I Named the zone is DMZ and creates rule SRC Zone "DMZ" Src network "Any" --- Destination Zone"Any" Destination network "branch ID "

2- RIP the Subnet

3- Static Routing: IP/netmask  Branche/24 + gateway my interface 172.30.30.1/30  and Port interface
