Our primary internet service went down but the backup did not work. I was able to connect remotely to the remote Sonicwall using the backup internet service's WAN IP address so I know it was at least connected properly.
The users at that location couldn't browse the internet and the VPN tunnel from that location to the headquarters was down.
What do you think might be causing this? The failover in the Sonicwall is setup properly.
The primary internet's WAN interface in the Sonicwall still shows that its "link" was still "up" when the internet was down.
