How to install VPN with SSTP for RRAS on Windows Server?
Install IIS and RRAS:
In Server Manager, Manager → Add Roles and Features, check Remote Access and Web Server (IIS).
In Features pane select Remote Server Administration Tools and all submodules and in Remote Access Role Services select DirectAccess, VPN and Routing.
Install WACS for LetsEncrypt.
https://github.com/win-acme/win-acme
Run rrasmgmt.msc
Right click server → Configure → Custom Configuration → VPN Access & Demand-dial connections
Start the service.
Right click the server → Properties
IPv4 tab, select static address pool and choose an appropriate IP range for VPN clients (e.g. 192.168.25.40 , 192.168.25.80)
Default Web Site host in IIS has an HTTPS binding, and the Server Name Identification box is UNTICKED! The host used for an SSTP VPN must NOT require SNI.
To get rid of any certificates for the VPN host. In admin terminal:
$hostname = "vpn.company.com"
Get-ChildItem -Path Cert:\LocalMachine\My | Where-Object {$_.Subject -match $hostname} | Remove-Item
Edit settings_default.json for 4096 bit key size.
C:\WACS\wacs.exe --ocsp-must-staple
Place the certificate in the Personal store explicitly and do ALL additional installation steps.
Doubleclick the .pfx --> import in Personal store
Finally, we can set our RRAS cert to the one we just created:
RRAS properties --> security --> SSTP certificate
LetsEncrypt certificates expire every 3 months, but WACS reschedules updates.
Startup RRAS by default on a machine boot:
Run services.msc
Find the Remote Access Connection Manager service, right-click → Properties → Startup type: Automatic
Do not use default gateway on remote network:
Open the Network and Sharing Center, and click into Change adapter settings. Right-click the VPN connection you just created, and select "Properties". Switch to the Networking tab.
Select the Internet Protocol Version 4 (TCP/IPv4) list item, then click the Properties button. Click Advanced, and uncheck Use default gateway on remote network.
Troubleshooting:
VPN user must be allowed to dial-in:
Run mmc.exe
Add the Local Users and Groups snap-in from the File menu
Click into your user account, then right-click Properties
Dial-in tab, Allow access under Network Access Permission
Network Policy Server must allow VPN connections
If you have NPS enabled, you will have to configure it to allow VPN connections.
Under the NPS snap-in from mmc.exe → Advanced Configuration → Network Policies → Grant access to both policies relating to VPN connections (they are deny by default).
Host machine must be discoverable:
Open up the Network and Sharing Center
Click Advanced sharing settings
Expand the Private and Guest or Public groups, and turn on Network Discovery and File and printer sharing on both.
All good?
AWESOME!
