Site to Site is Up, HQ to BO Ping okay, BO to HQ Ping loss.

Hi Team,

I have created IPSEC Site to Site and it's Up now.

But having an issue with the BO to Ping/ Access HQ failed.

From HQ to BO Ping/Access Success.

HQ - FortiGate 80F

BO - Sophos UTM 9

HQ subnet - 192.168.110.0

BO subnet - 192.168.1.0, 192.168.3.0

Updated: - Now its able to ping to HQ - FortiGate 80F - New issue is when SSL to HQ from other Network, it can access/ping HQ Servers, but it failed to access/ping to BO Server at the same time. - If SSL to BO from other Network, it can access/ping BO Servers, but it failed to access/ping to HQ Server at the same time. is it normal or I miss out route on this?
