Security

Remote Access Control

You can determine whether or not an administrator or other authorized person has access to configuring
your Gateway. This access can be turned on or off in the Web interface.

Password Protection

Access to your Motorola Netopia® device can be controlled through two access control accounts, Admin or
User.
• The Admin, or administrative user, performs all configuration, management or maintenance operations
on the Gateway.
The User account provides monitor capability only.
•
A user may NOT change the configuration, perform upgrades or invoke maintenance functions.
Account usernames can now be changed for the Admin and User accounts.

Network Address Translation (NAT)

The Motorola Netopia® Gateway Network Address Translation (NAT) security feature lets you conceal the
topology of a hard-wired Ethernet or wireless network connected to its LAN interface from routers on net-
works connected to its WAN interface. In other words, the end computer stations on your LAN are invisible
from the Internet.
Only a single WAN IP address is required to provide this security support for your entire LAN.
LAN sites that communicate through an Internet Service Provider typically enable NAT, since they usually
purchase only one IP address from the ISP.
When NAT is ON, the Motorola Netopia® Gateway "proxies" for the end computer stations on your net-
•
work by pretending to be the originating host for network communications from non-originating networks.
The WAN interface address is the only IP address exposed.
The Motorola Netopia® Gateway tracks which local hosts are communicating with which remote hosts. It
routes packets received from remote networks to the correct computer on the LAN (Ethernet) interface.
