Remote Access Control
You can determine whether or not an administrator or other authorized person has access
to configuring your Gateway. This access (either time-restricted or unlimited until the router
is rebooted) can be turned on or off in the Web inter face. Additionally, permanent remote
access can be configured in the CLI.
Password Protection
Access to your Motorola Netopia® device can be controlled through two access control
accounts,
Admin
or
User
.
• The
Admin
, or administrative user, per forms all configuration, management or mainte-
nance operations on the Gateway.
•
The
User
account provides monitor capability
only
.
A user may NOT change the configuration, per form upgrades or invoke maintenance
functions.
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
inter face from Gateways on networks connected to its WAN inter face. 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 suppor t for your entire
LAN.
LAN sites that communicate through an Internet Ser vice 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 sta-
tions on your network by pretending to be the originating host for network communica-
tions from non-originating networks. The WAN inter face address is the only IP address
exposed.
