3rd that. Outgoing telnet should be selecting a random port greater than 1023. 3389 is valid.

Totally agree. 3389 is not a well known port and is completely valid for
a source port number.

was 3389 the source port? Then get rid of that "security software"…

Betreff: Port 3389 (RDP)

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.
