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.

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. 

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 support 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.
