Security Level

Security level refers to how much access is permitted from your router to the Internet or other networks.

To enable and configure the security level feature:

1. Select Level from the “

Firewall Settings” window.

2. Click the Configure hyperlink next to Level. This displays the “Firewall Level Configuration” window.

3. Select the firewall security level from the Select Firewall Level drop-down menu. This can be one of

the following:

• Off

No firewall protection. Data can move freely both in and out of the router.

• Low

Provides basic firewall protection. Attack detection is enabled and only ports well known to the

router can allow the flow of data.

• High

Provides maximum firewall protection. Only certain applications are allowed through the firewall or

traffic that is already "in conversation" with an application from the host PC and host application.

(ICSA 3.0a Compliant.)

• Custom

Set your own rules for firewall protection. This option should be used by advanced users only. If

you select this option, you must set customized rules for both inbound and outbound traffic using

the

IP Filtering option.

4. Click Apply.
