The Firewall is now attached to the network.
By default, no traffic that originates from the Internet is allowed onto the
LAN, and all communications from the LAN to the Internet are allowed.
That is, all inbound connections are blocked and all outbound
connections are allowed.
You can now configure the Firewall. See the following chapters for more
information:
■
Chapter 3 for a quick setup guide for the Firewall.
■
Chapters 4 to 8 for full information about all the configuration
options.
■
Chapter 11 for information about the Web Site Filter and Network
Access Policy Rules.
At frequent intervals, check the Firewall for the following:
■
The Alert LED is not continuously lit — if it is, there are problems on
your network.
■
The case vents are not obstructed.
■
The cabling is secure and is not pulled taut.
