Trusted zone

The trusted zone represents a group of network addresses from which the firewall allows some inbound traffic using default settings. Settings for features like file sharing and remote desktop inside of the trusted zone are determined in Allowed services and advanced options.

The actual trusted zone is computed dynamically and separately for each network adapter based on what network the computer is currently connected to. Addresses defined as inside of the trusted zone in the Zones editor are always trusted. If a network adapter is connected to a known network, then the Additional trusted addresses configured for that network are added to the adapter's trusted zone. If a network has the Home/office protection type, all directly connected subnets are included in the trusted zone. The actual trusted zone for each network adapter can be viewed from the Setup window under Network > Network adapters.
