Typical Configuration 47
Setting Up Your
Computer If You Have a
Static IP Address
If your computer has a static IP address, you must verify and possibly change some
settings on your computer before you begin the LAN Modem configuration
procedure. The 56K LAN Modem must be your gateway to get outside of your
LAN as well as one of your DNS servers. Follow the procedure in the appropriate
section to make sure that this is the case. Note that if your computer has a
dynamic IP address, this configuration would occur automatically and you can go
on to “Configuring the 56K LAN Modem for the Typical Configuration”.
These instructions assume that the LAN Modem configuration is set the factory
default. If you are moving the LAN Modem from a different LAN, reset the LAN
Modem before you begin. To do so, refer to Chapter 8, “Resetting the 56K LAN
Modem to a Factory Default Setting”.
