Other than taking a screencap of my ruleset, and then retyping it all back in if I need to restore my system, does anyone know of a way to do this? Am I missing...

    Firewall Rules: Allowed IPs and Threat Prevention?

    Quick question, but probably one that betrays how little I actually understand Threat Prevention at the moment. If I create a firewall rule that allows traffic from a range of IPs, will threat prevention just ignore those? I use a particular remote desktop streaming service that's generating a...
