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 SG 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 SG 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 SG unit for information on its network ports and
possible configurations.
