Getting port forwarding to work on Hub 2

[#1]

Hi, I had port-forwarding working fine on my Hub 1, but cannot get the port to open on Hub2.

I've attached a screenshot of the rule that I created in the firewall section of the router webpage.   I have checked my Plusnet account and the firewall there is off.  What can cause the port to remain closed ? (using https://www.yougetsignal.com/tools/open-ports/ to check port  status)  Any helpwould be greatly appreciated !

Is 192.168.1.99 still the local address of the Arduino testrig, or has it changed?

Can you access the internal IP on port 84 when connected to the local network?

How are you trying to access the resource remotely?

Hello Bob, yes, I can access 192.168.1.99:84 locally. I am accessing remotely via NoIP (but have just thought that I SHOULD try my public address port 84 to see if that works !!)

Bob, public IP address:84 works OK.  Just thought, I seem to rmember having to tell the router that I was using NoIP so that it was informed of a public address change - will go hunting .... !!

OK - found DDNS on the Hub2 and it is OFF - That's my problem !!! MANY thanks for making me think !!
