Multifunction Vs. Fixed-Function Ports - Secure Computing SG300 User Manual

A network interface is configured by selecting a connection type from the Change Type
pull-down menu. The current configuration can be viewed or modified by clicking the
Edit icon. Clicking the Delete icon unconfigures a network interface; you are prompted
to confirm this action.

Multifunction vs. Fixed-function Ports

Some SnapGear units have network ports with labels corresponding to the port's
function, i.e. LAN, DMZ and Internet/WAN. These are said to be fixed-function ports.
Alternatively, some SnapGear units have network ports that are generically labeled, e.g.
port A, port B, port C. These are said to be multifunction ports. This reflects the ability of
these ports to perform many different functions, e.g. port B is not limited to connecting to
the Internet only, it may be configured as a LAN connection.
Note
Before beginning configuration of multifunction ports, you should determine which
function you are assigning to each of the ports.
Proceed to the section pertaining to your SnapGear unit for information on its network
ports and possible configurations.
