Using Windows 10 as a VPN host

VPN
1

Hi all!

I am currently setting up a W10 machine as a VPN host.
This computer has been used for this before, and no settings have changed other than a new router/modem combo.

The machine is set up as this article explains: https://pureinfotech.com/setup-vpn-server-windows-10/ (External link)

I have set up PPTP port forwarding to the computer (See below for Port Forwarding settings)

Name: PPTP
Protocol: TCP/UDP
WAN port to/from: 1723/1723
LAN port to/from: 1723/1723
LAN-IP: withheld

Upon connecting to the VPN I have set up, I get the error:

The network connection between your computer and the VPN server was interrupted. This can be caused by a problem in the VPN transmission and is commonly the result of internet latency or simply that your VPN server has reached capacity.

I also get this message on the properties for incoming connections:

No hardware capable of accepting calls is installed

I can’t remember this being there when I originally set this up, either way, it worked before the above mentioned router/modem combo replacement.

I have also checked that the following services are running:

Remote Access Connection Manager
IKE and AuthIP IPsec Keying Modules

Firewall is opened for incoming VPN connections.

​

Thanks in advance for any and all help.

IPSec needs UDP port 500 forwarding enabled.

Also enable IP protocol numbers 50 and 51 on both inbound and outbound firewall filters.

TCP 1723 is for data only, UDP 500 is security negotiation.

The PPTP protocol mentioned in that tutorial only uses TCP port 1723 for connection setup. Actual data are transmitted using the GRE protocol which is IP protocol 47. This is not a TCP/UDP port.

Some routers can pass it through using special rules or DMZ. I would google the router model and “GRE passthrough” or “PPTP passthrough”.

If your router doesn’t support it, you can try SoftEther which provides a very friendly graphical interface with a reasonably simple setup process. Note only the OpenVPN and SSTP protocols can work with TCP/UDP passthrough.
