Hey guys,
following problem:
We use a Sophos XGS 3300.
Internal Webserver is in DMZ Zone 10.10.10.0. It has an FQDN which will be resolved to an external IP on external DNS servers and to its internal IP on internal DNS servers.
From LAN and SSLVPN I can access through https://FQDN and its resolved by internal IP.
From IPSec Tunnel on our branch office, I can't access through https://FQDN. ICMP works and its resolved to internal IP.
If I access https://internal.ip from branch office, it works. https://FQDN will run into an error, something regarding TLS/SSL.
We had Sophos SG before and it worked, not sure which setting I'm missing on the XGS v19.
We don't use webserver protection, access comes through NAT, if that information is needed.
