NAT (Network Address Translation)
NAT allows PCs on your LAN to share a single external (Internet) IP Address. This IP Address
is supplied by your ISP. Use the following to determine whether or nor you need NAT.
•
For Internet access, NAT
must be left On
unless all PCs on your LAN have valid external
IP Addresses.
•
If this device is not being used to provide shared Internet access, NAT is not normally
required. With NAT disabled, the Broadband Router will act as a static router.
•
If NAT is disabled, the Firewall protection provided by the Broadband Router is lost, and
the
Advanced Internet
features (Virtual Servers, Special Applications, and DMZ) are no
longer available.
TFTP
TFTP (Trivial FTP) can be used to upgrade the firmware in the Broadband Router. However,
this is not normally required; there is a Windows utility available for this purpose.
Remote Management
This feature allows you to manage the Broadband Router via the Internet.
Enable Remote Man-
agement
Enable to allow management via the Internet. If Disabled, this
device will ignore management connection attempts from the
WAN port.
Port Number
Enter a port number between 1024 and 65535 (8080 is recom-
mended). This port number must be specified when you connect
(see below).
Note:
The default port number for HTTP (Web) connections is
port 80, but using port 80 here will prevent the use of a Web
"Virtual Server" on your LAN. (See
Advanced Internet - Virtual
Servers
)
Current WAN Port
IP Address
You must use this IP Address to connect (see below).
This IP Address is allocated by your ISP. But if using a Dy-
namic IP Address, this value can change each time you connect
to your ISP. So it is better if your ISP allocates you a Fixed IP
Address.
To connect from a remote PC via the Internet
1.
Ensure your Internet connection is established, and start your Web Browser.
2.
In the "Address" bar, enter "HTTP://" followed by the WAN IP Address of the Broadband
Router. If the port number is not 80, the port number is also required. (After the IP Ad-
dress, enter ":" followed by the port number.)
e.g.
HTTP://123.123.123.123:8080
This example assumes the WAN IP Address is 123.123.123.123, and the port number is
8080.
