11.8 Interface Technical Reference
Here is more detailed information about interfaces on the ZyWALL.
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
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
