TotalNET Advanced Server 5.2 Reference Manual

NB-nd-port

This attribute specifies the UDP destination port number for transmitting data to the NDA. If the network uses ENS, you should include this command on every ENSA on the network if the default port number 227 does not work, and also on all systems where the NDA resides. For port-number, specify a number from 0 to 65535. It should not exceed 1023. The default value generally suffices.

Usage:

tntransport -M -n tcpip -a NB-nd-port=port-number
