Always open for serial server discovery.
This port is used for discovering serial servers. This port is always open
no matter how you configure the device.
Note: The device discovery only works on a local subnet. The port may
not need to be configured in a firewall or NAT.
Other TCP and UDP ports may be open depending on what you specify
for the device configuration. THESE ARE THE PORTS SPECIFIED IN
THE CONFIGURATION FILE.
If you want to use these other ports from outside of a firewall, then you
must allow these ports.
If you want to use these other ports from outside of a NAT, then you
must forward to these ports
