Time Zone
The FVS124G VPN Firewall uses the Network Time Protocol (NTP) to obtain the current time
and date from one of several Network Time Servers on the Internet. In order to localize the time
for your log entries, you must specify your Time Zone:
• Time Zone. Select your local time zone. This setting will be used for the blocking schedule
and for time-stamping log entries.
• Daylight Savings Time. Check this box for daylight savings time.
Note: If your region uses Daylight Savings Time, you must manually select Adjust for
Daylight Savings Time on the first day of Daylight Savings Time, and unselect it at the
end. Enabling Daylight Savings Time will add one hour to the standard time.
Be sure to click Apply when you have finished configuring this menu.
Block Sites
If you want to reduce incoming traffic by preventing access to certain sites on the Internet, you can
use the VPN firewall's content and Web component filtering feature. By default, this feature is
disabled; all requested traffic from any Web site is allowed. When users try to access a blocked
site, they will get a message: Blocked by NETGEAR.
• 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.
