EE Blocking Ports 443 & 1723


I have received a new Huawei B593s-22 Router from EE and signed up to 50GB of mobile broadband data per month. I have a windows 2012 essentials server setup with 5 computers running Windows 7 pro 64 bit, the Internet works fine on all of the Computers and server.

I want to make use of Windows remote desktop services to allow me to access files via VPN and also remotely connect to PC's in the office, I have setup port forwarding for ports 443 and 1723 and still cannot get this to work. Previously I was with BT and used a Draytek router and everythin worked fine, do EE block ports 443 and 1723 on their mobile broadband services ? Is their a workaround to make RDS work ? Maybe use different ports ?

Any help much appreciated!

Is your new modem giving you an external IP address?  or is it giving an internal address provided for the modem's use. That may be the reason why this does not work.

I connect up with VPN, not directly, and it (a) is more secure and (b) allows a complete range of modems.

Then finally, what does EE mean here? You are posting to EE.

You can use this site its services to check for open ports

Also if im not mistaken, tcp 3389 is the internal RDP port for Windows. If you like to access it on port 443 (wouldnt recommend it) you need to be sure port 443 is being forwarded to tcp 3389 on the destination server by your router.

im not known with Huawei routers, but port forwarding from a vpn interface can be tricky. So i would recommend to simply allow port 3389 and connect using that.

Chris, EE means everything everywhere and is  UK mobile phone and mobile broadband provider. The router has an external address provided by EE and the internal address of the router is

Mobile broadband often uses a double NAT arrangement and therefore will prevent most port forwarding from working.

I think you might be still better off with VPN and one that can do NAT traversal.
