LABEL DESCRIPTION
Static DHCP Table
# This is the index number of the static IP table entry (row).
MAC Address Type the MAC address (with colons) of a computer on your LAN.

DNS Server
DNS Servers
Assigned by DHCP
Server
The Zyxel Device passes a DNS (Domain Name System) server IP address (in the order you
specify here) to the DHCP clients. The Zyxel Device only passes this information to the LAN
DHCP clients when you enable DHCP Server in the General screen. When you disable DHCP
Server, DHCP service is disabled and you must have another DHCP sever on your LAN, or
else the computers must have their DNS server addresses manually configured.
First DNS Server
Second DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS server information (and the
Zyxel Device's WAN IP address). The field to the right displays the (read-only) DNS server IP
address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS server's IP
address in the field to the right.
Select DNS Relay to have the Zyxel Device act as a DNS proxy. The Zyxel Device's LAN IP
address displays in the field to the right (read-only). The Zyxel Device tells the DHCP clients on
the LAN that the Zyxel Device itself is the DNS server. When a computer on the LAN sends a
DNS query to the Zyxel Device, the Zyxel Device forwards the query to the Zyxel Device's
system DNS server (configured in the WAN screen) and relays the response back to the
computer.
