10.16 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.

Table 83 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 because it is a point-to-point interface. For these interfaces, you can only enter the IP address.

In many interfaces, you can also let the IP address and subnet mask be assigned by an external DHCP server on the network. In this case, the interface is a DHCP client. Virtual interfaces, however, cannot be DHCP clients. You have to assign the IP address and subnet mask manually.

In general, the IP address and subnet mask of each interface should not overlap, though it is possible for this to happen with DHCP clients.
