See “Using a Schedule to Block or Allow Specific Traffic” on page 6-22 for the procedure on how
to use this feature.
Block Sites
If you want to reduce traffic by preventing access to certain sites on the Internet, you can use the
VPN firewall's filtering feature. By default, this feature is disabled; all requested traffic from any
Web site is allowed.
• Keyword (and domain name) blocking—You can specify up to 32 words that, should they
appear in the website name (i.e., URL) or in a newsgroup name, will cause that site or
newsgroup to be blocked by the VPN firewall.
You can apply the keywords to one or more groups. Requests from the PCs in the groups for
which keyword blocking has been enabled will be blocked. Blocking does not occur for the
PCs that are in the groups for which keyword blocking has not been enabled.
You can bypass keyword blocking for trusted domains by adding the exact matching domain
to the list of Trusted Domains. Access to the domains on this list by PCs even in the groups for
which keyword blocking has been enabled will still be allowed without any blocking.
• Web component blocking—You can block the following Web component types: Proxy, Java,
ActiveX, and Cookies. Sites on the Trusted Domains list are still subject to Web component
blocking when the blocking of a particular Web component has been enabled.
See “Block Sites” on page 6-24 for the procedure on how to use this feature.
Source MAC Filtering
If you want to reduce outgoing traffic by preventing Internet access by certain PCs on the LAN,
you can use the source MAC filtering feature to drop the traffic received from the PCs with the
specified MAC addresses. By default, this feature is disabled; all traffic received from PCs with
any MAC address is allowed.
See “Source MAC Filtering” on page 6-27 for the procedure on how to use this feature.
