IP Setup
Small Office models only
The Netopia ISDN Router uses Internet Protocol (IP) to communicate
both locally and with remote networks. This chapter shows you how
to configure the Router and to effectively route IP traffic. You also
learn how to configure the Router to serve IP addresses to hosts on
your local network.
Small Office models of the Netopia ISDN Router also include a
special IP feature called Network Address Translation (NAT).
NAT is a powerful feature that allows the user to represent an entire
LAN to the outside world as a single IP address. Instead of having a
separate IP address for each computer on the network, users now
need only one IP address called a proxy address.
