Unable to open Windows RDP Connection

[blkuhn]

I have setup a vpn connection between my Windows 10 PC (client) to a windows 10 PC (server) and I get a connected status from both the vpn client and server manager and I can ping both directions.
I am unable to open an RDP session from the client to the server. Both the vpn client and server permit RDP port 3389 thru their firewalls.
Do I need to turn on port forwarding in my router?

If you use NAT-T you don't need to.

I don't use NAT-T tho.... I stop SoftEther from listening on all ports but tcp 443... Then I open up tcp443 on my router and map it to my server. I also go into SoftEther client advanced settings and open up 16-20 tcp connections, enable half duplex mode, and disable udp acceleration. You can also enable data compression, if you want. but i don't.

Also you might have a issue if your trying to use RDP into the same computer the server is running on. I've never tried personally, but I know I've had issues trying to ssh into the computer the server is running on through VPN. SSH is expecting to receive a connection from LAN or an external IP but its coming from local loopback 127.0.0.0/8.

Did you configure SecureNAT or create a bridge?
I guess you connect RDP to 192.168.30.1.
If so, the IP address is SecureNAT virtual host. Try to connect to the actual IP address.
