I've had RCN for a decade and always had an inbound connection, via port 3389, to my desktop computer at home that I accessed from work. The connection stopped working in the past two weeks and I am wondering if this is RCN or not, just really curious.
There are three variables in play here all inside of the past two weeks:
1. I moved from the 50/5 to 155/15 package about two weeks ago. Called RCN, they switched me over the phone, and had new speeds.
2. I upgraded the firmware to my Netgear Nighthawk R7000 AC1900 router. I made sure all port mappings carried over and weren't messed with.
3. I upgraded my desktop from Windows 7 to Windows 10 (Pro) -- clean install. One of the first things I did was to enable remote access and make an exception in Windows firewall.
So it stopped working and I spend 30 minutes troubleshooting. I could RDP from inside my network just not outside. I validated the IP didn't change and my Dynamic DNS was still updating. Then it hit me....
So I changed the port mapping from 3389 (external) > 3389 (internal) to 3000 (external) > 3389 (internal) and boom, it worked again from outside the network.
Did RCN start blocking 3389 inbound traffic? That's the only reasonable explanation I have at the moment. :)
