IPSec Tunnel up, but not pinging

Hello All,


Though the question has been asked many times, I've setuo the IPSec Tunnel (Site2Site) between Sophos XG105 (SFOS 17.0.6 MR-6) and Cyberoam with 16.5 MR.

The tunnel is up and Active, but the internal IPs at both ends are not reachable. I can ping from Sophos to internal IPs of Sophos end and similarly from Cyberoam to Internal IPs of Cyberoam end.

Also, I've configured Static route for Internal subnets of opposite ends on both Sophos & Cyberoam.
