Gateway
Check this Select this to specify a domain name or IP address for the connectivity check. Enter that

DHCP Setting The DHCP settings are available for the OPT, LAN and DMZ interfaces.
DHCP Select what type of DHCP service the Zyxel Device provides to the network. Choices are:
None - the Zyxel Device does not provide any DHCP services. There is already a DHCP
server on the network.
DHCP Relay - the Zyxel Device routes DHCP requests to one or more DHCP servers you
specify. The DHCP server(s) may be on another network.
DHCP Server - the Zyxel Device assigns IP addresses and provides subnet mask, gateway,
and DNS server information to the network. The Zyxel Device is the DHCP server for the
network.
These fields appear if the Zyxel Device 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 Zyxel Device is a DHCP Server.
IP Pool Start Enter the IP address from which the Zyxel Device begins allocating IP addresses. If you want
Address
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 Zyxel Device 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 Zyxel Device 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 Zyxel Device
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.
