Adding the Remote Phone addressing
The Linksys Etherfast Cable/DSL router utilizes network address translation (NAT) to allow multiple
hosts to use the modem connection to the Internet and to provide limited security for those hosts.
Please follow the following steps to configure the router. (Instructions for connecting to the configuration
screen can also be found in the
Linksys Etherfast Cable/DSL Router User’s Guide
. Instructions for
configuring the Linksys router for specific ISPs can be obtained from the Linksys Web site,
www.linksys.com
.)
1.
On the user’s PC (assuming it’s properly configured to use the modem), open a Web browser and,
in the address field, enter the IP address of the modem. By default, that address is 192.168.1.1.
2.
The Web browser will load the configuration screen and should ask for your password. Enter the
system password if required.
3.
You should now be at the
Setup
menu. To allow the traffic bound for the phone through the router,
IP forwarding will need to be configured. (Instructions for setting up IP forwarding can also be found
in the
Linksys Etherfast Cable/DSL Router User’s Guide
.)

the
Setup
screen, click on the

Phone will be using in the Service Port field.
