Block network devices when running on backup internet

[floridanativ]

When we are failed over to backup internet, how can I create a policy to block our streaming music service and security camera service, until we roll back to primary internet?

Both devices responsible for these services are on our LAN.

If your backup is cellular then use the cellular firewall rules.

If your backup is WAN2 then you can raise a support ticket and ask to have the cellular firewall rules applied to WAN2.
