IP Address Assignment Most interfaces have an IP address and a subnet mask. This information is used to create an entry in the routing table. Figure 167 Example: Entry in the Routing Table Derived from Interfaces lan1 wan1 Table 70 Example: Routing Table Entries for Interfaces IP ADDRESS(ES) DESTINATION 100.100.1.1/16 lan1 200.200.200.1/24 wan1 For example, if the ZyWALL gets a packet with a destination address of 100.100.25.25, it routes the packet to interface lan1. If the ZyWALL gets a packet with a destination address of 200.200.200.200, it routes the packet to interface wan1. In most interfaces, you can enter the IP address and subnet mask manually. In PPPoE/PPTP interfaces, however, the subnet mask is always 255.255.255.255 266 ZyWALL USG 50 User's Guide
