Sep 20, 2018 · Similar to using a VPN, you can use your Windows firewall to limit access to your RDP port (by default, port 3389). The process of restricting access to a port to a single IP address or group of IP addresses is known as “scoping” the port. If the latter, port 3389 is already forwarded, but it doesn't mean you can't use it. Forward a random port by leaving the port field on the port forwarding page blank, but enter 3389 into the local port field. To test this, establish the VPN connection and try to telnet to the remote machine on port 3389 using the following command: C >telnet 3389 You need to forward port 3389 from your modem to your server to have this working from the outside! Take a look at portforward dot com if you need help forwarding ports on your modem. [edit] I’m sorry, I must be thinking RDP. 3389 (tcp) is for RDP and won’t help with VPN. Hola: I went into my MHS291LVW and I enabled port forwarding. I didn't see an option for Remote Desktop (RDP) so I added a custom application called RDP and I set "Global Port" and "Private Port" to port number 3389 and I set it as TCP/UDP and then entered the local IP (192.168.1.135) of the PC I want to connect to. not VPN'd in, that connects to TS over the internet. Normally, he can connect just fine. I had him test and he can telnet port 3389 just fine. It seems to stay connected, and he has to close the cmd window using the window's X button (I couldn't figure out how else to exit the telnet session).

Cisco Jabber IM Screen share - port 3389 blocked I wanted to see if anyone had knowledge on if port 3389 is required for Cisco Jabber IM Screen Share. UDP Port 3389 was recently blocked on our Client VPN solution, and we now can't Screen Share via the Cisco Jabber IM method.

you do not need to forward port 3389 through the router because there is a vpn tunnel created. That tunnel allows all traffic [no firewall] but if the hosts have firewall, then you have to allow it.

External Resources SANS Internet Storm Center: port 3389. Notes: Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. Change the listening port for Remote Desktop. Changing the listening port will help to "hide" Remote Desktop from hackers who are scanning the network for computers listening on the default Remote Desktop port (TCP 3389). This offers effective protection against the latest RDP worms such, as Morto. To do this, edit the following registry key Similarly, IPSec-based VPN that provides a higher level of security utilizes several ports for security, such as IP port numbers 50 and 51 for Encapsulated Security Protocol (ESP) and Authentication Header (AH), respectively. It also utilizes UDP port 500 and 4500 for phase 1 and 2 negotiations.
