FIELD DESCRIPTION EXAMPLE
First DNS Server
Second DNS
Server
Third DNS
Server
The HomeSafe passes a DNS (Domain Name System) server IP
address (in the order you specify here) to the DHCP clients.
Select From ISP if your ISP dynamically assigns DNS server
information (and the HomeSafe's WAN IP address). The IP Address
field below 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 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 HomeSafe act as a DNS proxy. The
HomeSafe's LAN IP address displays in the IP Address field below
(read-only). The HomeSafe tells the DHCP clients on the LAN that the
HomeSafe itself is the DNS server. When a computer on the LAN sends
a DNS query to the HomeSafe, the HomeSafe forwards the query to the
HomeSafe'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.
From ISP
DHCP Server
Address If Relay is selected in the DHCP field above, then type the IP address of
the actual, remote DHCP server here.
