This section introduces the ZyWALL’s default zone member physical interfaces and
the default configuration of those interfaces. The following figure uses letters to
denote public IP addresses or part of a private IP address.
Figure 50 Default Network Topology
Table 14 ZyWALL USG 20 Default Port, Interface, and Zone Configuration
• The WAN zone contains the wan1 interface (physical port P1). It uses a public
IP address to connect to the Internet.
• The LAN1 zone contains the lan1 interface (a port group made up of physical
ports P2 and P3 on the ZyWALL). The LAN1 zone is a protected zone. The lan1
interface uses 192.168.1.1 and the connected devices use IP addresses in the
192.168.1.2 to 192.168.1.254 range.
