Setup Tab - Password

The Router's default User Name and Password is

Router's password from the default to a unique password.

Old Password. Enter the old password. The default Password is

admin

when you first power up the Router.

(The password cannot be recovered if it is lost or forgotten. If the password is lost or forgotten, you have to reset

the Router to its factory default settings, which will remove all of your configuration changes.)

New Password. Enter a new password for the Router. Your password must have 15 or fewer characters and

cannot contain any spaces.

Confirm New Password. Re-enter the new password to confirm it.

Setup Tab - Time

The Router uses the time settings to time stamp log events, automatically update the Content Filter List, and

perform other activities for other internal purposes.

Chapter 6: Setting up and Configuring the Router

Setup Tab - DMZ Host

10/100 16-Port VPN Router

Setup Tab - DMZ Host

The DMZ (Demilitarized Zone) Host feature allows one local user to be exposed to the Internet for use of a

special-purpose service such as Internet gaming or video conferencing. Although Port Range Forwarding can

only forward 10 ranges of ports maximum, DMZ hosting forwards all the ports to one PC at the same time.

In the

DMZ Private IP Address

field, enter the local IP address of the computer you want to expose. The default

value of 0 deactivates the DMZ Host.

Click the

Save Settings

button to save your change, or click the

Cancel Changes

button to undo the change.

Setup Tab - Forwarding

The

Forwarding

screen allows you to set up port range forwarding and port triggering applications. Port range

forwarding can be used to set up public services or other specialized Internet applications on your network, while

port triggering can be used to set up triggered ranges and forwarded ranges for Internet applications.

Port Range Forwarding

Port forwarding can be used to set up public services on your network. When users from the Internet make

certain requests on your network, the Router can forward those requests to computers equipped to handle the

requests. If, for example, you set the port number 80 (HTTP) to be forwarded to IP address 192.168.1.2, then all

HTTP requests from outside users will be forwarded to 192.168.1.2.

You may use this function to establish a web server or FTP server via an IP gateway. Make sure that you enter a

valid IP address. (You may need to establish a static IP address in order to properly run an Internet server.) For

added security, Internet users will be able to communicate with the server, but they will not actually be

connected. The packets will simply be forwarded through the Router.

Click the

button, and configure as many entries as you would like, up to a maximum of 30. To

delete an entry, select it and click the

Delete selected application

Port Triggering

Port triggering allows the Router to watch outgoing data for specific port numbers. The IP address of the

computer that sends the matching data is remembered by the Router, so that when the requested data returns

through the Router, the data is pulled back to the proper computer by way of IP address and port mapping rules.

Some Internet applications or games use alternate ports to communicate between the server and LAN host.

When you want to use these applications, enter the triggering (outgoing) port and alternate incoming port in the

Port Triggering table. Then the Router will forward the incoming packets to the LAN host.

1.

For each application, complete the

Application Name

,

Trigger Port Range

, and

Incoming Port Range

fields.

Click the

Chapter 6: Setting up and Configuring the Router

Setup Tab - One-to-One NAT

10/100 16-Port VPN Router

Setup Tab - One-to-One NAT

One-to-One NAT (Network Address Translation) creates a relationship that maps valid external addresses to

internal addresses hidden by NAT. Devices with internal addresses may be accessed at the corresponding

external IP addresses, as long as they are valid.

To create this relationship between internal and external addresses, define internal and external address ranges

of equal length. (The Router’s WAN IP address may not be included in the range of external addresses.) Once that

relationship is defined, the device with the first internal address is accessible at the first IP address in the

external address range, the second device at the second external IP address, and so forth.

For example, consider a LAN to which the ISP has assigned external IP addresses ranging from 209.19.28.16 to

209.19.28.31, with 209.19.28.16 used as the Router’s WAN IP (NAT public) address.The internal address range of

192.168.168.1 to 192.168.168.255 is used for the devices on the LAN. Typically, only devices that have been

designated as public LAN servers will be accessible from the Internet. However, with One-to-One NAT, the

machines with the internal IP addresses of 192.168.168.2 to 192.168.168.15 may be accessed at the

corresponding external IP addresses.

One-to-One NAT does not change how the firewall functions work. Access to LAN devices from the Internet will

not be allowed unless the appropriate network access rules are established, the appropriate forwarding entries

are enabled, or the appropriate authenticated user sessions are established.

Before configuring the One-to-One NAT settings, set up the appropriate Access Rules on the

Firewall - Access

Rules

screen, or set up the appropriate forwarding entries on the

Setup - Forwarding

screen.

To use the One-to-One NAT feature, click the

Enable

box. To set up a One-to-One NAT entry, follow these

instructions:

1.

In the

Private Range Begin

field, enter the beginning IP address of the private address range being mapped.

This will be the IP address of the first machine that will be accessible from the Internet.

2.

In the

Public Range Begin

field, enter the beginning IP address of the public address range being mapped.

(This will be assigned by the ISP.) The Router’s WAN IP (NAT public) address cannot be included in this range.

3.

Enter the number of IP addresses in the

Range Length

field. This number may not exceed the number of valid

external IP addresses. To map a single address, use a Range Length of 1.

4.

Click the

Add to list

button, and configure as many ranges as you would like, up to a maximum of 64. To

delete an entry, select it and click the

Delete selected range

button.

Click the

Save Settings

button to save your settings, or click the

Cancel Changes

button to undo your changes.
