Secure Computing SG300 User Manual page 82

Caution is advised before allowing machines on a Guest network direct access to the
Internet, particularly in the case of Guest wireless networks. This may result in
unauthorized use of your Internet connection for sending spam, other malicious or illegal
activities, or simply Internet access at your expense.
Machines on the Guest network typically have addresses in a private IP address range,
such as 192.168.2.0 / 255.255.255.0 or 10.2.0.0 / 255.255.0.0. For network address
translation (NAT) purposes, the Guest connection is considered a LAN interface, i.e. the
NAT checkboxes for LAN interfaces under Advanced modify settings for both LAN
connections and Guest connections. See the Network address translation section later in
this chapter for further information.
Configuring a Guest connection
Select Direct Connection from the Configuration pull-down box of the network port to
be connected to the Guest network. Enter appropriate IP address settings and select
Guest from Firewall Class pull-down menu.
Configuring a Direct Connection is described in detail in the section entitled Direct
Connection towards the beginning of this chapter.
