Broadband ADSL2+ Modem DM111PSPv2 For example, if your external address is 134.177.0.123 at port number 8080, enter the following in your browser: http://134.177.0.123:8080 Note: The http:// is required in the address. Static Routes Static routes provide additional routing information to your modem. Under normal circumstances, the modem has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes.Configure static routes only for unusual cases, such when you have multiple routers or multiple IP subnets 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 modem on your home network for connecting to the company where you are employed. This modem's address on your LAN is 192.168.0.100. • Your company's network address is 134.177.0.0. When you first configured your modem, two implicit static routes were created. A default route was created with your ISP as the broadband ADSL2+ modem, 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 modem 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 modem that 134.177.0.0 should be accessed through the ISDN modem at 192.168.0.100. 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 are to be forwarded to the ISDN modem at 192.168.0.100. • The value in the Metric field represents the number of modems between your network and the destination. This is a direct connection, so it can be set to the minimum value of 2. • The Private check box is selected only as a precautionary security measure in case RIP is activated. Advanced Settings 61

Broadband ADSL2+ Modem DM111PSPv2
For example, if your external address is 134.177.0.123 at port number 8080, enter the
following in your browser:
Note:
The http:// is required in the address.
Static Routes
Static routes provide additional routing information to your modem. Under normal
circumstances, the modem has adequate routing information after it has been configured for
Internet access, and you do not need to configure additional static routes.Configure static
routes only for unusual cases, such when you have multiple routers or multiple IP subnets 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 modem on your home network for connecting to the company where
you are employed. This modem’s address on your LAN is 192.168.0.100.
•
Your company’s network address is 134.177.0.0.
When you first configured your modem, two implicit static routes were created. A default route
was created with your ISP as the broadband ADSL2+ modem, 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 modem 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 modem that 134.177.0.0 should be
accessed through the ISDN modem at 192.168.0.100.
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 are to be
forwarded to the ISDN modem at 192.168.0.100.
•
The value in the
Metric
field represents the number of modems between your network
and the destination. This is a direct connection, so it can be set to the minimum value
of
2.
•
The
Private
check box is selected only as a precautionary security measure in case RIP
is activated.
