We have two SA520W devices with firmware 2.2.0.7. Each device has two Internet connections with static public IP addresses.
The goal is to have the VPN tunnel between the devices come up when the Internet rollover occurs. As long as the main Internet connection stays up, the VPN tunnel works. We have been unsuccessful so far using the administration guide as it only tells you about the rollover option and the backup tunnel option. No examples appear to have been provided.
How can this be accomplished?
