Interface

 

Parameters

 

 

 

Egress

Enter the maximum amount of traffic, in kilobits per second, the

Bandwidth

ZyWALL can send through the interface to the network. Allowed values

 

are 0 - 1048576. This setting is used in WAN load balancing and

 

bandwidth management.

 

 

Ingress

This is reserved for future use.

Bandwidth

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.

 

 

MTU

Maximum Transmission Unit. Type the maximum size of each data

 

packet, in bytes, that can move through this interface. If a larger

 

packet arrives, the ZyWALL divides it into smaller fragments. Allowed

 

values are 576 - 1500. Usually, this value is 1500.

 

 

DHCP Settings

 

 

 

DHCP

Select what type of DHCP service the ZyWALL provides to the wireless

 

network. Choices are:

 

None - the ZyWALL does not provide any DHCP services. There is

 

already a DHCP server on the network.

 

DHCP Relay - the ZyWALL routes DHCP requests to one or more

 

DHCP servers you specify. The DHCP server(s) may be on another

 

network.

 

DHCP Server - the ZyWALL assigns IP addresses and provides subnet

 

mask, gateway, and DNS server information to the network. The

 

ZyWALL is the DHCP server for the network.

 

 

 

These fields appear if the ZyWALL is a DHCP Relay.

 

 

Relay Server 1

Enter the IP address of a DHCP server for the network.

 

 

Relay Server 2

This field is optional. Enter the IP address of another DHCP server for

 

the network.

 

 

 

These fields appear if the ZyWALL is a DHCP Server.

 

 

IP Pool Start

Enter the IP address from which the ZyWALL begins allocating IP

Address

addresses.

 

If this field is blank, the ZyWALL assigns every IP address allowed by

 

the interface’s IP address, subnet mask, and pool size; except for the

 

first address (network address), last address (broadcast address) and

 

the interface’s IP address.
