DSM 7.2 has a point where it says in order to continue it must break your port forwarding. So it does, and everything goes a little wonky. For example, Active Backup for Business agent broke. The Synology router has a forward of traffic to port 3333; on Synology, the application receives traffic on port 3333. Then when you try to connect the Mac desktop Active Backup for Business agent wizard says: Internet error. please check your connection.
Has anyone else hit this issue?
