What actual dynamic port range

[vitaleg]

The documentation says that Netmaker needs one port per network, starting from 51821 to 518XX (udp). But in my case I see that ports in a much larger range are used, both up and down.

For example:

bash-5.1# netstat -anp
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
...
udp 0 0 0.0.0.0:57422 0.0.0.0:* -
udp 0 0 :::57422 :::*

What is the actual port range used for nodes?
