If your dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use wildcards check box to activate this feature. For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. 8. Click Apply to save your configuration. Using Static Routes Static routes provide additional routing information to your modem router. Under normal circumstances, the modem 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. Static Route Example 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. When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the modem router, 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 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. Advanced Configuration 5-9 v1.0, May 2008

Using Static Routes
Static routes provide additional routing information to your modem router. Under normal
circumstances, the modem 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.
Static Route Example
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.
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the modem router, 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 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.
