You can change TCP-port number used by USB over Network Server.
For this, on the Settings menu click Preferences then click Network tab and specify new TCP-port number.
Please note that the changes will only take effect for new connections, and will not apply to existing connections.
Enable UPnP port mapping
If you have a UPnP-compatible network router, you can enable this option for simplified local network access as well as remote access via the Internet.
All USB over Network Clients must be reconfigured to use the same TCP-port number as USB over Netowork Server does (refer to Changing the Network Settings in USB over Network Client help).
In some situations it is convenient to identify computers with USB over Network installed by their unique Aliases. You can specify the Alias Name of the current computer and choose whether to show aliases of other computers instead of hostnames.
