In the Port Triggering Timeout field, enter a value up to 9999 minutes.
This value controls the inactivity timer for the designated inbound ports. The inbound
ports close when the inactivity time expires. This value is required because the router
cannot be sure when the application has terminated.
5.
Click
Add Service
to display the following screen:
6.
In the Service Name field, type a descriptive service name.
7.
In the Service User list, select
Any
(the default) to allow this service to be used by any
computer on the Internet. Otherwise, select
Single address
, and enter the IP address of
one computer to restrict the service to a particular computer.
8.
Select the service type, either
TCP
or
UDP
or both (
TCP/UDP
). If you are not sure, select
TCP/UDP.
9.
In the Triggering Port field, enter the number of the outbound traffic port that causes the
inbound ports to open.
10.
Enter the inbound connection port information in the Connection Type, Starting Port, and
Ending Port fields.
11.
Click
Apply
. The service appears in the Port Triggering Portmap table.
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 is, 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.
On the
ADVANCED
tab, select
Advanced > Dynamic DNS
to display the following screen:
To set up Dynamic DNS:
1.
Register for an account with one of the Dynamic DNS service providers whose URLs
appear in the Service Provider list.
2.
Select the
Use a Dynamic DNS Service
check box.
3.
Select the URL of your Dynamic DNS service provider. For example, for DynDNS.org,
select
www.dyndns.org
.
4.
Type the host name (or domain name) that your Dynamic DNS service provider gave you.
5.
Type the user name for your Dynamic DNS account. This name is the name that you use to
log in to your account, not your host name.
6.
Type the password (or key) for your Dynamic DNS account.
7.
Click
Apply
to save your configuration.
Static Routes
Static routes provide more routing information to your router. Under usual circumstances, the
router has adequate routing information after it has been configured for Internet access, and
you do not need to configure more 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.
Page 78 / 103

•
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
get 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 since 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 > Static Routes
to display the following screen:

2.
Click
Add
to display the following screen:
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 a router 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 connection is a direct connection, set it to 1.
10.
Click
Apply
to add the static route.
Remote Management
The remote management feature lets you upgrade or check the status of your router over the
Internet.

To set up remote management:
1.
Select
ADVANCED > Advanced > Remote Management
.
Note:
Be sure to change the router’s default login password to a secure
password. The ideal password should contain no dictionary words from any
language and contain uppercase and lowercase letters, numbers, and
symbols. It can be up to 30 characters.
2.
Select the
Turn Remote Management On
check box.
3.
Under Allow Remote Access By, select the extent of external IP addresses that are allowed
access to 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 is 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 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 through 65535, but do not use the number of any common service
port. The default is 8080, which is a common alternate for HTTP.
