5. Select the Port Triggering radio button.
The page adjusts.
6. Clear the Disable Port Triggering check box if it is selected.
Note: If the Disable Port Triggering check box is selected after you configure
port triggering, port triggering is disabled. However, any port triggering
configuration information you added to the modem router is retained
even though it is not used.
7. 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 closure is required because the modem
router cannot be sure when the application has terminated.

The Port Triggering -Services page displays.
9. In the Service Name field, type a descriptive service name.
10. 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.
11. Select the service type, either TCP or UDP or both (TCP/UDP). If you are not sure, select
TCP/UDP.
12. In the Triggering Port field, enter the number of the outbound traffic port that causes the
inbound ports to be opened.
13. Enter the inbound connection port information in the Service Type, Starting Port, and Ending
Port fields.
14. Click the Apply button.
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 works because private addresses are not routed on the Internet.
Your modem router contains a client that can connect to the Dynamic DNS service provided
by DynDNS.org. First visit their website at
