LABEL	DESCRIPTION
Interface
Parameters
Egress	Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can
Bandwidth	send through the interface to the network. Allowed values are 0 - 1048576.
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 Setting
DHCP	Select what type of DHCP service the ZyWALL provides to the 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 addresses. If
Address	you want to assign a static IP address to a specific computer, click Add Static
	DHCP.
	If this field is blank, the Pool Size must also be blank. In this case, the ZyWALL
	can assign every IP address allowed by the interface’s IP address and subnet
	mask, except for the first address (network address), last address (broadcast
	address) and the interface’s IP address.
Pool Size	Enter the number of IP addresses to allocate. This number must be at least one
	and is limited by the interface’s Subnet Mask. For example, if the Subnet Mask
	is 255.255.255.0 and IP Pool Start Address is 10.10.10.10, the ZyWALL can
	allocate 10.10.10.10 to 10.10.10.254, or 245 IP addresses.
	If this field is blank, the IP Pool Start Address must also be blank. In this case,
	the ZyWALL can assign every IP address allowed by the interface’s IP address
	and subnet mask, except for the first address (network address), last address
	(broadcast address) and the interface’s IP address.
First DNS Server	Specify the IP addresses of a maximum of three DNS servers that the network
Second DNS	can use. The ZyWALL provides these IP addresses to DHCP clients. Use one of
Server	the following ways to specify these IP addresses.
Third DNS	Custom Defined - enter a static IP address.
Server
	From ISP - select the DNS server that another interface received from its DHCP
	server.
	ZyWALL - the ZyWALL uses the IP address of this interface and works as a
	DNS relay.
