Why would single port forwarding suddenly stop working?

by nukolas . Updated 16 years, 6 months ago

I recently created 5 port forwards for 5 individual users to remotely connect to their machines in the office from home. I designated the port numbers in the router (Linksys WRT300N) and pointed them to their static IP addresses. I also changed their default port number in their Windows registry on their machines. All steps were covered and I was able to successfully connect to their machines from outside of the domain.

Essentially, it works like this. From my PC I use remote desktop and connect to their domains public IP address and tack on their port number at the end.

66.16.XX.XX:3394

All was working great but now, nothing. Also, if I attempt to remote desktop to their machines within the domain (say from the DC) I get that annoying error stating; “the client could not connect to the remote computer.” I CAN ping their IPs.

It’s all very confusing and for the life of me I can’t wrap my head around it. Any help would be greatly appreciated!

Please let me know if any other details are required.
