Connecting Mini PIMs to an Untrusted Network
Figure 10 shows the SSG 20 with basic network cabling connections with two blank
mini-PIMs and the 10/100 Ethernet ports cabled as follows:
The port labeled 0/0 (ethernet0/0 interface) is connected to the untrust
network.
The port labeled 0/1 (ethernet0/1 interface) is connected to a workstation in the
DMZ security zone.
The port labeled 0/3 (bgroup0 interface) is connected to a workstation in the
Trust security zone.
The Console port is connected to a serial terminal for management access.
