That's not one of the ports that are used in Navigator, so I would not
expect to see it.
The closest is 3825 which is the debug server, clearly not what you're

Anyone know why a Power 9 system running v7r3 would use TCP port 3389 to
contact a telnet device (Motorola/Zebra Radio Frequency device running 5250
telnet)?

This occurred yesterday and the security software on our firewall shut
down access from that network to the IBM system.

TIA,
