Stateful Packet Inspection (SPI) is a firewall architecture that works at the network layer.
Unlike legacy static packet filtering, which examines a packet based on the information in its
header, stateful inspection builds up a state machine to track each connection traversing all
interfaces of the firewall and makes sure they are valid. The stateful firewall of Vigor router
not just examine the header information also monitor the state of the connection.
The purpose of this is to enable the SPI firewall for the filtering incoming packets and
outgoing packets. Simply check the box and click OK.

We all know that the content on the Internet just like other types of media may be
inappropriate sometimes. As a responsible parent or employer, you should protect those in your
trust against the hazards. With Web filtering service of the Vigor router, you can protect your
business from common primary threats, such as productivity, legal liability, network and
security threats. For parents, you can protect your children from viewing adult websites or chat
rooms.
Once you have activated your Web Filtering service in Vigor router and chosen the categories of
website you wish to restrict, each URL address requested (e.g.www.bbc.co.uk) will be checked
against our server database. This database is updated as frequent as daily by a global team of
Internet researchers. The server will look up the URL and return a category to your router. Your
Vigor router will then decide whether to allow access to this site according to the categories you
have selected. Please note that this action will not introduce any delay in your Web surfing
because each of multiple load balanced database servers can handle millions of requests for
categorization.
