We have a Draytek 2830 onsite that is used as the VPN server which remote users have been able to connect into fine for months. This morning suddenly all users gets error 800.
There is another company that manages the internet connection and state that nothing has changed.
As far as we know the router under our control nothing has changed.
We have not actually restarted the router yet, which most likely (hopefully will resolve it) but as this will bring everyone in the office down for a short while want to avoid it.
Is there anyway of doing a test to ensure that a firewall someone is not blocking the VPN ports?
