Port Number

The setting represents the source port number in TCP connections. It is the number that identifies the channel for remote initiating connections. The default setting for Port 1 is 10001. The range is 1-65535, except for the following reserved port numbers:

Warning: We recommend that you not use the reserved port numbers for this setting as incorrect operation may result.

The port number functions as the TCP/UDP source port number for outgoing packets. Packets sent to the unit with this port number are received to this channel. The port number selected is the Incoming TCP/UDP port and Outgoing TCP/UDP source port. Use Port 0 when you want the outgoing source port to change with each connection.

If the port number is 0, a random value of at least 50000 is used to actively establish a connection. Each subsequent connection increments the number by 1. When the port number reaches 59999, it wraps around to 50000.

Only use the automatic port increment feature to initiate a connection using TCP. Set the port to a non-zero value when the unit is in a passive mode or when you are using UDP instead of TCP.
