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.

In other situations, NAT is not normally required. With NAT disabled, the CNWR-811P will act as a static router.

If NAT is disabled, the Firewall protection provided by the CNWR-811P 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 CNWR-811P. However, this is not normally required; there is a Windows utility available for this purpose.

Remote Management

This feature allows you to manage the CNWR-811P via the Internet.

Enable Remote

Enable to allow management via the Internet. If Disabled, this

Management

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

You must use this IP Address to connect (see below).

IP Address

This IP Address is allocated by your ISP. But if using a Dynamic 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 CNWR- 811P. If the port number is not 80, the port number is also required. (After the IP Address, 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.
