Whilst trying to connect to a SonicWall VPN recently, I came across the below prompt, which wouldn’t allow me on to the VPN:
Thankfully the solution was fairly simple:
Open the Sonic Wall VPN Client.
Choose the VPN you are trying to connect to and then properties.
Navigate to the peers tab and choose edit.
At the bottom of the below pop up, change Interface Selection to “LAN Only”.
Once you restart the VPN Client, you will be able to connect without issue.
