CHAPTER 6 Configuring Firewall
Settings
The Firebox® X Edge uses services and other firewall options to control
the traffic between the trusted, optional, and external networks. The
configuration of allowed services and firewall options set the level of
security the Firebox applies to your network.
About Services
A Firebox® service is one or more rules that together monitor and con-
trol traffic. These rules set the firewall actions for a service:
• Allow lets data or a connection through the Firebox.
• Deny stops data or a connection from going through the Firebox,
and sends a response to the source.
• No Rule sets a rule to off, as if the rule was not defined. This
option is available to allow you to manage only the incoming or
only the outgoing properties of a service.
For example, to operate a Web server behind the Firebox X Edge, con-
figure the HTTP service to let incoming traffic flow to the IP address of
the Web server (the internal computer that receives the requests for
Web pages).
