Hello,
if you set up a session like e.g. ping won't work (DNS error).

Hello,
The Port of your session should not affect the Ping, because ping doesn't look at the ports, therefore the issue could be somewhere else.
Note that we do have a Port Scan feature that you could use instead. 
Best Regards,
