Something had to had changed on the SonicWall for this to happen. How many people have administrative access to the firewall?
If the SonicWall is not servicing other VPN tunnels, which based on what I'm seeing here seems to be true, go into the admin GUI and make sure the firewall is not listening for VPNs. You'll find this section under the VPN section and then just uncheck the enable VPN in the Global VPN settings.
