We had 3 WAN interfaces (Port E1, E4 and E5) on our XG210 HA. Firewall(s) are managed trough Sophos Central. After changing to a new single WAN connection on Port A1 and disabling the old WAN interfaces we receive alerts about missing heartbeats. The source is not a computer but the firewalls name is reported as source. So I guess its the heartbeat from the firewall to Sophos Central. What can I do? WAN connectivity is perfect and I can't find any related setting.
