NAT
Enable NAT
NAT (Network Address Translation) is the technology which allows
all PCs on your LAN to share the Internet IP address allocated to the
WAN port on this Router. From the Internet, all PCs appear to have
the same IP address.
For normal operation, this setting must be ENABLED.
Disable NAT Disabling NAT will disable Internet access, unless all PCs have
valid Internet IP addresses.
If you wish to use this device for Routing ONLY (and NOT for
Internet access), then NAT should be disabled.
DNS
Automatically
obtain from
Server
The DNS (Domain Name Server) address will be obtained automati-
cally from your ISP's server. Note that if using a fixed IP address,
with no login (login is set to "None"), then no Server is used, and this
option cannot be used.
Use this DNS
If this option is selected, you must enter the IP address of the DNS
(Domain Name Server) you wish to use.
Note: If the DNS is unavailable, the "Backup DNS", entered on the
Internet - Options screen, will be used.
