The Netopia R9100 provides a number of security features to help protect its configuration screens and your
local network from unauthorized access. Although these features are optional, it is strongly recommended that
you use them.

Suggested security measures
In addition to setting up user accounts, Telnet access, and filters (all of which are covered later in this chapter),
there are other actions you can take to make the Netopia R9100 and your network more secure:
■
Change the SNMP community strings (or passwords). The default community strings are universal and
could easily be known to a potential intruder.
■
Set the answer profile so it must match incoming calls to a connection profile.
■
Set the Enable Dial-in Console Access option to No.
■
When using AURP, accept connections only from configured par tners.
■
Configure the Netopia R9100 through the serial console por t to ensure that your communications cannot
be intercepted.
User accounts
When you first set up and configure the Netopia R9100, no passwords are required to access the configuration
screens. Anyone could tamper with the router’s configuration by simply connecting it to a console.
However, by adding user accounts, you can protect the most sensitive screens from unauthorized access. User
accounts are composed of name/password combinations that can be given to authorized users.
