Remote PC and public IP

[Guest]

I have 2 pc's in my LAN which work well with remote desktop.
But...if I try to connect with another pc outside my LAN, I cannot
connect to the host.

I tried it also with remote desktop web connection.
As long as the pc"s are part of the LAN it works.
NO connection from pc to the host.

I opened port 3389 on the host
my IP: 82.174.228.18

You need to forward TCP port 3389 in your firewall/router, to the LAN IP of
whatever computer you want to connect to - you can't connect to both using
that port.
You can change the RD listening port on one of the computers to something
else, like 3390, though....and then connect to x.x.x.x:3390

(best not to post your true public IP in here, honestly)

.. . . and it's changed here on the host machine:
HKLM\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\Por

If I ping to the local address (host PC address) I can see that port 3389:TCP
is listening.
but my public IP address doesnt respond at all.
I have forwarded port 3389 in TCP and UDP on the firewall/router
I assume to connect to (public) ip: x.x.x.x:3389, but still doesnt work?

Help !!!

You can't use ping.exe to test a port number - use
telnet instead:

telnet aaa.bbb.ccc.ddd 3389
