Reference Manual for the ProSafe VPN Firewall FVS114

•Turn Cookies filtering on: Block all cookies.

Note: Many Web sites will not function correctly if these components are blocked.

Keyword Blocking: To enable keyword blocking, check Turn keyword blocking on, then click Apply.

•To add a keyword or domain, type it in the Keyword box, click Add Keyword, then click Apply.

•To delete a keyword or domain, select it from the list, click Delete Keyword, then click Apply.

Keyword application examples:

•If the keyword "XXX" is specified, the URL <http://www.badstuff.com/xxx.html> is blocked, as is the newsgroup alt.pictures.XXX.

•If the keyword “.com” is specified, only Web sites with other domain suffixes (such as .edu or

.gov) can be viewed.

•If you wish to block all Internet browsing access, enter the keyword “.”.

Trusted User: To specify a Trusted User, enter that PC’s IP address in the Trusted User box and click Apply.

You may specify one Trusted User, which is a PC that will be exempt from blocking and logging. Since the Trusted User will be identified by an IP address, you should configure that PC with a fixed or reserved IP address.

Using Rules to Block or Allow Specific Kinds of Traffic

Firewall rules are used to block or allow specific traffic passing through from one side to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine what outside resources local users can have access to.

A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of the FVS114 are:

•Inbound: Block all access from outside except responses to requests from the LAN side.

•Outbound: Allow all access from the LAN side to the outside.
