FIELD
First DNS Server The ZyWALL passes a DNS (Domain Name System) server IP address (in
the order you specify here) to the DHCP clients.
Second DNS
Server Select From ISP if your ISP dynamically assigns DNS server information
(and the ZyWALL's WAN IP address). The IP Address field below displays
Third DNS Server
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 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 menu 1) 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.
If Relay is selected in the DHCP field above, then type the IP address of the
DHCP Server
Address actual, remote DHCP server here.
Use the instructions in the following table to configure TCP/IP parameters for the LAN port.
LAN and DMZ IP addresses must be on separate subnets.
FIELD
TCP/IP Setup:
