Enable SmartStart/SmartView/Web Server

You may wish to restrict access to the web-based screens to prevent inadvertent switching or connecting and disconnecting of Connection Profiles. Since SmartStart can be used to reconfigure the router, you may wish to block inadvertent damage resulting from unauthorized use of SmartStart. To prevent access to these features toggle this option to “No”.

Telnet access

Telnet is a TCP/IP service that allows remote terminals to access hosts on an IP network. The Netopia R2121 supports Telnet access to its configuration screens.

Caution!

You should consider password-protecting or restricting Telnet access to the Netopia R2121 if you suspect there is a chance of tampering.

To password-protect the configuration screens, select Easy Setup from the Main Menu, and go to the Easy Setup Security Configuration screen. By entering a Name and Password pair in this screen, all access via serial, Telnet, SNMP, and web server will be password-protected.

To restrict Telnet access, select Security in the Advanced Configuration Menu and go to the Security Options screen. There are two levels of Telnet restriction available:

To restrict Telnet access to the SNMP screens, select Enable Telnet Access to SNMP Screens and toggle it to No. (See “SNMP traps” on page 13-15.)

To restrict Telnet access to all of the configuration screens, select Enable Telnet Console Access and toggle it to No.

About filters and filter sets

Security should be a high priority for anyone administering a network connected to the Internet. Using packet filters to control network communications can greatly improve your network’s security.

The Netopia R2121’s packet filters are designed to provide security for the Internet connections made to and from your network. You can customize the router’s filter sets for a variety of packet filtering applications. Typically, you use filters to selectively admit or refuse TCP/IP connections from certain remote networks and specific hosts. You will also use filters to screen particular types of connections. This is commonly called firewalling your network.

Before creating filter sets, you should read the next few sections to learn more about how these powerful security tools work.

What’s a filter and what’s a filter set?

A filter is a rule that lets you specify what sort of data can flow in and out of your network. A particular filter can either be an input filter—one that is used on data (packets) coming in to your network from the Internet—or an output filter—one that is used on data (packets) going out from your network to the Internet.

A filter set is a group of filters that work together to check incoming or outgoing data. A filter set can consist of a combination of input and output filters.
