I have 2 firewalls. Firewall A is a XG and Firewall B is an SG
A ---- B
On A x.x.x.x/24 can ping on B x.x.x.x/24 and vice versa
However on the A side if you browse to the webpage of that device such as a esxi host or synology on the B side it timesout.
But if you browse from B to A it works just fine.
Firewall rule shows any server. I can see the HTTPS packets passing thru both firewalls as allowed.
Thank you for contacting the Sophos Community.
What versions of the XG and UTM are you running?
This sounds like a MTU issue, try running a packet capture to see if you find fragmented packets…
