Each server in the community must have access (via the LAN or WAN) to the IP address of the SyncServer hub on port 9769.
If you use our interface file to configure your solution, the machine this is running from must have access to each server node IP address in the community on port 9779. Alternatively each server node can be deployed independently and port 9779 only needs to be open locally to each server.
The JDBC port for your database (i.e.: port 2399 for FileMaker Server) must be open to the SyncServer Engine.
