Sometimes they disable ports if they feel that there is too much traffic over those ports. These ISPs operate by their own rules and if they feel that you are violating any rule they can and will stop you. However, if you explain to them what you are trying to accomplish they may aid you. Good Luck. + 0 Votes Reponse To Answer thetominator 2 years ago OK. Figured it out by myself. It wasn't the cable company blocking the port, it was my Kaspersky Internet Security 2012 Firewall that was doing it. I just decided today to see if it had anything blocking it and saw the Firewall, so I turned it off to test it and it worked. Now, I have it back on with the RD unselected in the Settings, Firewall, settings, Packet Rules tab. + 0 Votes It's not particularly weird, ISP may be blocking 80 outbound. seanferd 2 years ago Surfing the web uses 80 inbound for the most part. Since ISPs frequently disallow hosting of webservers for home customers, your service may not be reachable on 80 HTTP. But is the RDP service forwarded on 80 at your router and computer firewalls? Is the target computer expecting the user account you are now using to connect to it? Does your DDNS hosting service correctly have the current IP updated without an error?
