Hi,
Which TMOS version do you have? Could you post your Virtual Servers configuration?
Just for curiosity I did the test in different versions of TMOS without this abnormal behavior in BIG-IP.
This is the behavior in my lab:
telnet f5labs.test.lab 1720
Connecting To f5labs.test.lab...Could not open connection to the host, on port 1720: Connect failed
nmap -sT -p 1720 f5labs.test.lab
Starting Nmap ... Nmap scan report for f5labs.test.lab ... Host is up.
PORT STATE SERVICE
