Following is the list of network communication ports used by the Arsenal Database Server in Point of Success version 2.5 and above. If you are manually configuring a firewall, open these ports on both the client and server computers.
UDP Ports (Used for server discovery broadcast messages) - 22009 and 22010
TCP Ports (Used for exchanging data with the database server) - 22007 and 22008
Opening specific firewall ports is only necessary if allowing Point of Success executables through the firewall has failed.
