Connecting the Device to a Network 23
Connecting the Device to a Network
An SSG 140 device provides firewall and general security for networks when it is
placed between internal networks and the untrusted network. This section
describes the following:
Connecting an SSG 140 Device to an Untrusted Network
Connecting the Device to an Internal Network or a Workstation
Connecting an SSG 140 Device to an Untrusted Network
You can connect your SSG 140 device to an untrusted network in one of the
following ways:
Connecting Ethernet Ports
Connecting Serial (AUX/Console) Ports
Connecting PIMs
Figure 10 shows basic network cabling connections for an SSG 140 device. The
built-in 10/100 Fast Ethernet ports are cabled as follows:
The port labeled 0/0 (ethernet0/0 interface) is connected to a switch that
connects workstations on the Trusted LAN.
The port labeled 0/1 (ethernet0/1 interface) is connected to a switch that
connects workstations on the DMZ LAN; the remaining ports are not
connected.
The port labeled 0/2 (ethernet0/2 interface) is connected to the Untrust zone.
The Console port is connected to a serial terminal for management access.
