To configure the router as a repeater:
1.
Log in to the router that will be the repeater.
2.
Select
Basic > Wireless Settings
and
verify that the wireless settings match the base unit
exactly.
The wireless security option has to be set to
WEP
or
None
.
3.
Select
Advanced > Wireless Repeating Function
.
4.
Select the
Enable Wireless Repeating Function check box.
5.
Select
the
Wireless Repeater
radio button.
6.
Fill in the Repeater IP Address field.
This IP address has to be in the same subnet as the base station, but different from the
LAN IP address of the base station.
7.
(Optional) Select the
Disable Wireless Client Association
check box to prevent wireless
clients from associating with the repeater and allowing LAN client associations only.
You can leave the check box cleared if you prefer wireless clients to be able to associate
with the repeater.
8.
In the Base Station MAC Address field, enter the MAC addresses for the access point that
should function as the base station.
9.
Click
Apply
.
Your changes are saved.
10.
Verify connectivity across the LANs.
A computer on any wireless or wired LAN segment of the router can connect to the
Internet or share files and printers with any other computer or server connected to the
other access point.

Dynamic DNS
If your Internet service provider (ISP) gave you a permanently assigned IP address, you can
register a domain name and have that name linked with your IP address by public Domain
Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP
address, you do not know in advance what your IP address will be, and the address can
change frequently. In this case, you can use a commercial Dynamic DNS service. This type
of service lets you register your domain to their IP address and forwards traffic directed at
your domain to your frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic
DNS service does not work because private addresses are not routed on the Internet.
Your router contains a client that can connect to the Dynamic DNS service provided by
DynDNS.org. First visit their website at
and obtain an account and
host name that you configure in the router. Then, whenever your ISP-assigned IP address
changes, your router automatically contacts the Dynamic DNS service provider, logs in to
your account, and registers your new IP address. If your host name is hostname, for
example, you can reach your router at http://hostname.dyndns.org.
To set up Dynamic DNS:
1.
Select
Advanced > Advanced Setup > Dynamic DNS
.
2.
Register for an account with one of the Dynamic DNS service providers whose URLs are in
the Service Provider list.
For example, for DynDNS.org, select
www.dyndns.org
.
3.
Select the
Use a Dynamic DNS Service
check box.
4.
Select the URL of your Dynamic DNS service provider.
5.
Type the host name (or domain name) that your Dynamic DNS service provider gave you.
6.
Type the user name for your Dynamic DNS account.
This is the name that you use to log in to your account, not your host name.
7.
Type the password (or key) for your Dynamic DNS account.
8.
Click
Apply
.
Your changes are saved.

Static Routes
Static routes provide more routing information to your router. Typically, you do not need to
add static routes. You have to configure static routes only for unusual cases such as multiple
routers or multiple IP subnets on your network.
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 192.168.1.100.
Your company’s network address is 134.177.0.0.
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 192.168.1.x addresses. With this configuration, if you attempt to access a
device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP
forwards your request to the company where you are employed, and the request is likely to
be denied by the company’s firewall.
In this case you have to define a static route, telling your router that 134.177.0.0 should be
accessed through the ISDN router at 192.168.1.100. In this example:
The Destination IP Address and IP Subnet Mask fields specify that this static route
applies to all 134.177.x.x addresses.
The Gateway IP Address field specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.1.100.
A metric value of 1 works because the ISDN router is on the LAN.
Private is selected only as a precautionary security measure in case RIP is activated.
To set up a static route:
1.
Select
Advanced > Advanced Setup > Static Routes
.
2.
Click
Add.
3.
In the Route Name field, type a name for this static route (for identification purposes only.)
4.
Select the
Private
check box if you want to limit access to the LAN only.
If Private is selected, the static route is not reported in RIP.
5.
Select the
Active
check box to make this route effective.

6.
Type the IP address of the final destination.
7.
Type the IP subnet mask for this destination. If the destination is a single host, type
255.255.255.255
.
8.
Type the gateway IP address, which has to be on the same LAN segment as the router.
9.
Type a number from 1 through 15 as the metric value.
This value 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.
10.
Click the
Apply
button.
The static route is added.
To edit or delete a static route:
1.
Select
Advanced > Advanced Setup > Static Routes
.
The Static Routes screen displays.
2.
In the table, select the radio button next to the route that you want to edit or delete.
3.
Do one of the following:
Click the
Edit
button.
The Static Routes screen adjusts.
a.
Edit the route information.
b.
Click the
Apply
button.
Click the
Delete
button.
The route is removed from the table.
Remote Management
The remote management feature lets you access your router over the Internet to view or
change its settings.
Note:
Be sure to change the router default login password to a secure
password. The ideal password contains no dictionary words from
any language and contains uppercase and lowercase letters,
numbers, and symbols. It can be up to 30 characters. See
Change
the Password
on page
83.

To set up remote management:
1.
Select
Advanced > Advanced Setup > Remote Management
.
2.
Select the
Turn Remote Management On
check box.
3.
Under Allow Remote Access By, specify the external IP addresses to be allowed to access
the router’s remote management.
Note:
For enhanced security, restrict access to as few external IP addresses
as practical.
To allow access from a single IP address on the Internet, select
Only This Computer
.
Enter the IP address that will be allowed access.
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.
To specify IP addresses, select
IP Address List
and type in the allowed IP
addresses.
To allow access from any IP address on the Internet, select
Everyone
.
4.
Specify the port number for accessing the web management interface.
Normal web browser access uses the standard HTTP service port 80. For greater
security, enter a custom port number for the remote web management interface. Choose
a number from 1024 to 65535, but do not use the number of any common service port.
The default is 8080, which is a common alternate for HTTP.
5.
Click the
Apply button
.
Your changes take effect.
6.
When you access your router from the Internet, type your router’s WAN IP address into your
browser’s address or location field 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,
enter
in your browser.
