3) for when a rule is to be applied. Once a schedule is configured, it affects all rules that
use this schedule. You specify the days of the week and time of day for each schedule.
(See “Setting a Schedule to Block or Allow Specific Traffic” on page 61 for the procedure
on how to use this feature.)
Blocking 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 website is allowed.
Keyword (and Domain Name) Blocking. You can specify up to 32 words that, should
they appear in the website name (that is, 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 Trusted Domains table. Access to the domains in this table 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 table are still subject to Web
component blocking when the blocking of a particular Web component has been enabled.
See “Blocking Internet Sites (Content Filtering)” on page 62 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 “Configuring Source MAC Filtering” on page 64 for the procedure on how to use this
feature.
