Advanced Configuration

6-9

For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See

“IP

Configuration by DHCP

” on

page B-10

for an explanation of DHCP and information about how to

assign IP addresses for your network.

If another device on your network will be the DHCP server, or if you will manually configure the

network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.

Otherwise, leave it checked.

Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP

Address. These addresses should be part of the same IP address subnet as the router’s LAN IP

address. Using the default addressing scheme, you should define a range between 192.168.0.2 and

192.168.0.253, although you may wish to save part of the range for devices with fixed addresses.

The router will deliver the following parameters to any LAN device that requests DHCP:

•

An IP Address from the range you have defined

•

Subnet Mask

•

Gateway IP Address (the router’s LAN IP address)

•

Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;

otherwise, the router’s LAN IP address)

•

Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu

Using Address Reservation

When you specify a reserved IP address for a PC on the LAN, that PC will always receive the

same IP address each time it access the router’s DHCP server. Reserved IP addresses should be

assigned to servers that require permanent IP settings.

To reserve an IP address:

1.

Click the Add button.

2.

In the IP Address box, type the IP address to assign to the PC or server.

(choose an IP address from the router’s LAN subnet, such as 192.168.0.X)

3.

Type the MAC Address of the PC or server.

(Tip: If the PC is already present on your network, you can copy its MAC address from the

Attached Devices menu and paste it here.)

4.

Click Apply to enter the reserved address into the table.

Advanced Configuration

Note: The reserved address will not be assigned until the next time the PC contacts the router's

DHCP server. Reboot the PC or access its IP configuration and force a DHCP release and renew.

To edit or delete a reserved address entry:

1.

Click the button next to the reserved address you want to edit or delete.

2.

Click Edit or Delete.

How to Configure Static Routes

Static Routes provide additional routing information to your router. Under normal circumstances,

the router has adequate routing information after it has been configured for Internet access, and

you do not need to configure additional static routes. You must configure static routes only for

unusual cases such as multiple routers or multiple IP subnets located on your network.

From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the

Static Route menu, shown below.

Figure 6-4.

Static Route Summary Table

To add or edit a Static Route:

1.

Click the Add button to open the Add/Edit Menu, shown below.

Figure 6-5.

Static Route Entry and Edit Menu

2.

Type a route name for this static route in the Route Name box under the table.

(This is for identification purpose only.)

3.

Select Private if you want to limit access to the LAN only. The static route will not be reported

in RIP.

4.

Select Active to make this route effective.

5.

Type the Destination IP Address of the final destination.

6.

Type the IP Subnet Mask for this destination.

If the destination is a single host, type 255.255.255.255.

7.

Type the Gateway IP Address, which must be a router on the same LAN segment as the router.

8.

Type a number between 1 and 15 as the Metric value.

This represents the number of routers between your network and the destination. Usually, a

setting of 2 or 3 works, but if this is a direct connection, set it to 1.

9.

Click Apply to have the static route entered into the table.

As an example of when a static route is needed, consider the following case:

•

Your primary Internet access is through a cable modem to an ISP.

•

You have an ISDN router on your home network for connecting to the company where

you are employed. This router’s address on your LAN is 192.168.0.100.

•

Your company’s network is 134.177.0.0.

Advanced Configuration

When you first configured your router, two implicit static routes were created. A default route was

created with your ISP as the gateway, and a second static route was created to your local network

for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the

134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your

request to the company where you are employed, and the request will likely be denied by the

company’s firewall.

In this case you must define a static route, telling your router that 134.177.0.0 should be accessed

through the ISDN router at 192.168.0.100. The static route would look like

Figure 6-5

.

In this example:

•

The Destination IP Address and IP Subnet Mask fields specify that this static route applies to

all 134.177.0.x addresses.

•

The Gateway IP Address fields specifies that all traffic for these addresses should be

forwarded to the ISDN router at 192.168.0.100.

•

A Metric value of 1 will work since the ISDN router is on the LAN.

•

Private is selected only as a precautionary security measure in case RIP is activated.

Enabling Remote Management Access

Using the Remote Management page, you can allow a user or users on the Internet to configure,

upgrade and check the status of your WGR614 router.

To configure your router for Remote Management:

1.

Select the Turn Remote Management On check box.

2.

Specify what external addresses will be allowed to access the router’s remote management.

Note:

For enhanced security, restrict access to as few external IP addresses as practical.

a.

To allow access from any IP address on the Internet, select Everyone.

Note:

Be sure to change the router's default configuration password to a very secure

password. The ideal password should contain no dictionary words from any language,

and should be a mixture of letters (both upper and lower case), numbers, and symbols.

Your password can be up to 30 characters.

b.

To allow access from a range of IP addresses on the Internet, select IP address range.

Enter a beginning and ending IP address to define the allowed range.

c.

To allow access from a single IP address on the Internet, select Only this PC.

Enter the IP address that will be allowed access.

3.

Specify the Port Number that will be used for accessing the management interface.

Web browser access normally uses the standard HTTP service port 80. For greater security,

you can change the remote management web interface to a custom port by entering that

number in the box provided. Choose a number between 1024 and 65535, but do not use the

number of any common service port. The default is 8080, which is a common alternate for

HTTP.

4.

Click Apply to have your changes take effect.

Note:

When accessing your router from the Internet, you will type your router's WAN IP address

into your browser's Address (in IE) or Location (in Netscape) box, followed by a colon (:) and the

custom port number. For example, if your external address is 134.177.0.123 and you use port

number 8080, you must enter

http://134.177.0.123:8080

in your browser.

Using Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,

access the network and connect to other devices as needed. UPnP devices can

automatically discover the services from other registered UPnP devices on the network.
