Q: Does PDQ Link use split tunneling?

A: Yes!

Q: How do I check if my port is forwarded after the installation is complete?

A: You can use Test-NetConnection -port 443 to your server that you completed the PDQ Link setup on.

Q: How do I retrieve the certificate that was generated from the installation?

A: You can access the certificate from the cert store on the server you're completed the PDQ Link setup on using the password you chose during the installation.

Q: How do I check which User Group I granted access to connect to my server?

A: Network Policy Server -> Policies

Q: How many clients can connect to my PDQ Link server at once?

A: By default, the PDQ Link setup limits the server to 200 concurrent connections.

Q: How can I increase the maximum number of connections allowed to my PDQ Link server?

A: The number of connections to your PDQ Link server is governed by the number of SSTP ports configured in the Routing and Remote Access role. This number can be set using the Set-VpnServerConfiguration command in PowerShell. The following line will set the maximum connections to 500:

Set-VpnServerConfiguration -SstpPorts 500

After changing the number of SSTP ports on your sever, you'll need to restart the Remote Access service. This can be done by running this line of PowerShell:

Restart-Service RasMan -Force
