Unable to RDP to Port 3389 from outside network

Hi All,
I have RDP'd to 192.168.1.3:3389 fine from another laptop on the same network. However, when I try the same thing with my external IP address it isn't working. I have set up port forwarding on my r7000 (Advanced Tomato) for both TCP/UDP for port 3389 - and pointed it at 192.168.1.3. It seems as though the port forwarding is being ignored. If this port can't be opened - does anyone know some that can?
Thanks,
Mark

have you made sure that the extra plus.net "broadband firewall" is set to allow, as by default common ports are blocked. go to https://portal.plus.net/my.html?action=firewall to check

Hi Dahnak,
That did sound very promising! Unfortunately that setting seems to be off, I did try setting it to Low then back off again - still no joy though. It's almost as if all ports are blocked. I tried turning my firewalls off temporarily but with no effect - shouldn't be that anyway as I was able to RDP from within the network.
Thanks,
Mark

Hi Mark,
I have done a little bit of poking around, as logic says it should work.
After looking at the firewall rules for RDP on windows 10, I noticed the following setting on the entry for both remote desktop on UDP and TCP, in the advanced tab, there is an option called "Edge Traversal" which is turned on by default. This will block any RDP connections from outside your network from successfully connecting. presumably you will need to change this on both UDP and TCP rules
just be aware of the security implications from allowing full internet RDP
