Defining Trusted Interfaces

The Trusted Interface Page allows network manager to define Trusted interfaces.
Trusted interfaces are connected to DHCP servers, switches, or hosts which do not
require DHCP packet filtering. Trusted interfaces receive packets only from within
the network or the network firewall, and are allowed to respond to DHCP requests.
Packets sent from an interface outside the network, or from beyond the network
firewall, are blocked by trusted interfaces.
Conversely, untrusted interfaces can be configured to receive traffic from outside the
network or the firewall.
