Question : Remote Desktop Connection/RDP Issues - Trying to connect to workstation within a domain behind firewall

Hi,

I am having a few issues with allowing a user to connect from their home machine to their machine in the office on our domain.  I have enabled terminal services on the machines and have also enabled remote desktop.  

I have specified firewall rules to use port 14000.  I have also setup NAT to resolve the external IP to an internal IP with the specified port number.  The firewall is a Watchguard Firebox.

The user will be connecting from their home machine, with a Dynamically assigned IP.

Am I missing something here?

Thanks

Answer : Remote Desktop Connection/RDP Issues - Trying to connect to workstation within a domain behind firewall

Do you have a static IP or dynamic DNS hostname for the office?
Have you statically assigned the internal IP address to the host machine?
Have you changed the RDP port number on the host machine to match the port number you are opening/mapping to in the firewall?
Have you opened the port in the firewall/antivirus software on the host machine?

Backup your registry first, just in case of a mishap.

To change the RDP port number on the host machine (always recommended)
Regedit
HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
Modify PortNumber
Select Decimal
Change Port Number to mapped port in firewall
click OK
close regedit & reboot
