First DNS The ZyWALL passes a DNS (Domain Name System) server IP address
Server (in the order you specify here) to the DHCP clients.
Second DNS
Select From ISP if your ISP dynamically assigns DNS server information
Server
(and the ZyWALL's WAN IP address). The IP Address field below
Third DNS
displays the (read-only) DNS server IP address that the ISP assigns.
Server
Select User-Defined if you have the IP address of a DNS server. Enter
the DNS server's IP address in the IP Address field below. If you chose
User-Defined, but leave the IP address set to 0.0.0.0, User-Defined
changes to None after you save your changes. If you set a second choice
to User-Defined, and enter the same IP address, the second User-
Defined changes to None after you save your changes.
Select DNS Relay to have the ZyWALL act as a DNS proxy. The
ZyWALL's LAN IP address displays in the IP Address field below (read-
only). The ZyWALL tells the DHCP clients on the LAN that the ZyWALL
itself is the DNS server. When a computer on the LAN sends a DNS query
to the ZyWALL, the ZyWALL forwards the query to the ZyWALL's system
DNS server (configured in the SYSTEM General screen) and relays the
response back to the computer. You can only select DNS Relay for one of
the three servers; if you select DNS Relay for a second or third DNS
server, that choice changes to None after you save your changes.
Select None if you do not want to configure DNS servers. If you do not
configure a DNS server, you must know the IP address of a machine in
order to access it
