# Problem #1: Keeping certain programs from being accessed from certain external networks/VLANs
# Solution #1: Isolate that service in a container system that automatically fowards the ports to the right network interface(s)
# Solution #2: Don't open the firewall for these services, manually open the ports instead for the specific network interface(s) (trickier and easy to miss ports or ports can change)
# Untrusted network list:
# - VLANs [cameras]
# Problem #2: Untrusted internal services. Prevent them from accessing certain internal services (usually key unauth'd services like frigate)
# Solution #1: Isolate the untrusted services into their own container
# Untrusted services list:
# - Unifi? (it already has access to the cameras anyway?)
# - torrenting, *arr (worried about vulns)
