Gateway
Select this to use the default gateway for the connectivity check.
Check this
address
Select this to specify a domain name or IP address for the connectivity check. Enter that
domain name or IP address in the field next to it.

. Specify the port number to
use for a TCP connectivity check.
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
Address
Enter the IP address from which the Zyxel Device begins allocating IP addresses. If 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 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.
First DNS Server
Second DNS
Server
Third DNS Server
Specify the IP addresses up to three DNS servers for the DHCP clients to use. Use one of the
following ways to specify these IP addresses.
Custom Defined
- enter a static IP address.
From ISP
- select the DNS server that another interface received from its DHCP server.
Zyxel Device
- the DHCP clients use the IP address of this interface and the Zyxel Device
works as a DNS relay.
First WINS Server,
Second WINS
Server
Type the IP address of the WINS (Windows Internet Naming Service) server that you want to
send to the DHCP clients. The WINS server keeps a mapping table of the computer names
on your network and the IP addresses that they are currently using.
