8.16 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.
Figure 164 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 because it is a point-to-point
interface. For these interfaces, you can only enter the IP address.
IP Address
Assignment
IP Address Enter the IP address for this interface.
Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet
mask indicates what part of the IP address is the same for all computers in the
network.
Interface
Parameters
Egress
Bandwidth Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
send through the interface to the network. Allowed values are 0 - 1048576.
Ingress
Bandwidth This is reserved for future use.
Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
receive from the network through the interface. Allowed values are 0 - 1048576.
