Router User’s Guide

Monitoring Network Health

Level

The firewall contained within the Router may be configured to operate in one of several modes, referred to as levels. For ease of use, three generic levels are preconfigured – Low, Medium and High. A separate level, ICSA 3.0a Compliant, is provided for those users who require compliance with the criteria set forth by ICSA Labs for firewall behavior. (Please refer to Appendix D, “Firewall Security Levels,” in the User Guide on CD-ROM for a detailed description of these preconfigured levels.)

In addition to the preconfigured levels, a Custom level is provided for advanced users who require the capability to define a unique custom set of firewall rules. To specify the firewall security level:

1.Select Setup>Firewall>Level from the left navigation pane of the Web interface. This displays the “Firewall Level Configuration” window.

2.Select one of the following from the Select Firewall Level drop-down menu.

•Off

No restrictions are applied to either inbound or outbound traffic. In addition, Network Address Port Translation (NAPT) functionality is disabled. Because there is no address/port translation when the firewall is placed in this mode, all LAN-side connected hosts must be assigned a valid public IP address.

•Low

Minimal restrictions with respect to outbound traffic. Outbound traffic is allowed for all supported IP-based applications and Application Level Routers (ALGs). The only inbound traffic allowed is traffic received within the context of an outbound session initiated on the local host.

•Medium

Moderate restrictions with respect to outbound traffic. Outbound traffic is allowed for most supported IP-based applications and Application Level Routers (ALGs). The only inbound traffic allowed is traffic received within the context of an outbound session initiated on the local host.

•High

High restrictions with respect to outbound traffic. Outbound traffic is allowed only for a very restricted set of supported IP-based applications and ALGs. The only inbound traffic allowed is traffic received within the context of an outbound session initiated on the local host and permitted by this firewall mode.

•ICSA 3.0a-compliant

Supports the ICSA Labs criteria for firewall behavior. (For more information, visit the ICSA site at http://www.icsalabs.com).

•Custom

Allows advanced users to add, modify, and delete their own firewall rules. If you select this option, you must set customized rules for both inbound and outbound traffic using the IP Filtering option.

3.Click Apply.
