Dns clients not updating
First, you need to configure port forwarding on your router.You will need to know what port your application uses, and also the internal network IP address of the machine you’re using to serve that application.Next, to the hostname, you will see the IP address that we are currently resolving to.
It will take 60 seconds for the changes to fully propagate to the new IP address.
Next to the hostname that you need to update click “Modify”.
On the next page, under the Hostname Information window, you will see a location to change the IP address.
Simply put the port number you want to test, 22 in our example, in the box marked What Port? Our server will attempt a connection directly to your IP address and let you know the results.
Anything other than a response like the one below indicates something is wrong.
