Security Level
Security level refers to how much access is permitted from your Gateway 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 Gateway.
• Low
Provides basic firewall protection. Attack detection is enabled and only ports well known to the
Gateway 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.
