Determine the rewall zone to which your interface should be assigned. The
following options are available:
Firewall Disabled
This option is available only if the rewall is disabled and the rewall does
not run at all. Only use this option if your machine is part of a greater network
that is protected by an outer rewall.
Automatically Assign Zone
This option is available only if the rewall is enabled. The rewall is running
and the interface is automatically assigned to a rewall zone. The zone which
contains the keyword any or the external zone will be used for such an in-
terface.
Internal Zone (Unprotected)
The rewall is running, but does not enforce any rules to protect this interface.
Use this option if your machine is part of a greater network that is protected
by an outer rewall. It is also useful for the interfaces connected to the inter-
nal network, when the machine has more network interfaces.
Demilitarized Zone
A demilitarized zone is an additional line of defense in front of an internal
network and the (hostile) Internet. Hosts assigned to this zone can be reached
from the internal network and from the Internet, but cannot access the internal
network.
External Zone
The rewall is running on this interface and fully protects it against oth-
er—presumably hostile—network trafc. This is the default option.
