Access to Windows RDP only via VPN

jaceobmorgan · Post by **jaceobmorgan** » Wed May 13, 2020 5:49 am

Hi,

I'm a beginner, I installed OpenVPN for the first time on Windows Server 2019 and on a private computer with Windows 10. The VPN configuration was correct because the connection to the server is what I see in the OpenVPN logs on the server. In Firewall settings I changed that port 3389 would be open to the local network. After this change, I am connecting to the server by the old method (using public IP server: 60.50.40.30:3389) and I get a connection error and this is good. However, when I try to connect by local address, I cannot connect via RDP to the server.

Windows 10 - local network

What else should I do or check?

Does RDP really requires VPN usage? If yes, why?and by using vpn speed couldn't be comprise?

Port 3389 opened in the Firewall to public enables attack attempts.
I see several thousand attempts a day in the logs.

Re: Access to Windows RDP only via VPN

Make sure RDP is listening and the firewall is open. I can see no reason that RDP will not work over the VPN except by user changes.

However, this is strange:

Wed May 13 08:44:50 2020 Initialization Sequence Completed
Wed May 13 08:44:50 2020 MANAGEMENT: >STATE:1589352290,CONNECTED,SUCCESS,10.8.0.6,[IP_PUBLIC_SERVER],1194,,
Wed May 13 09:44:43 2020 TLS: soft reset sec=0 bytes=74821/-1 pkts=951/0

I don't see how this fits with the config you have posted.

This would require --reneg-bytes 73000 ?

Try using --verb 4 as advised.
