Default Device Settings
This section describes the default settings and operation of an SSG 20 device.
Table 5 shows the default zone bindings for ports on the devices.
Table 5: Default Physical Interface to Zone Bindings
A bridge group (bgroup) is designed to allow network users to switch between wired
and wireless traffic without having to reconfigure or reboot the device. By default,
the ethernet0/2 — ethernet0/4 interfaces, labeled as ports 0/2 — 0/4 on the device,
are grouped together as the bgroup0 interface, have the IP address 192.168.1.1/24,
and are bound to the Trust security zone. You can configure up to four bgroups.
If you want to set an Ethernet or a wireless interface into a bgroup, you must first
make sure that the Ethernet or wireless interface is in the Null security zone.
Unsetting the Ethernet or wireless interface that is in a bgroup places the interface
in the Null security zone. Once assigned to the Null security zone, the Ethernet
interface can be bound to a security zone and assigned a different IP address.
