Additional DC behind another Interface

Hi CreateShare,

Thank you for reaching out to Sophos Community.

For AD replication, a firewall rule will be required in order to communicate between two separate interfaces.

Hi CreateShare,

Thank you for reaching out to Sophos Community.

For AD replication, a firewall rule will be required in order to communicate between two separate interfaces.

Of course, the rule any to any for both the DCs is already there. Just needed to confirm if any special requirements.

No additional communication will be required. Only a firewall rule to allow them to communicate in between.
