This section highlights some differences in terminology or organization between the 
ZyWALL and other routers, particularly ZyNOS routers.

If you want to configure the ZyWALL effectively, you should understand the differences 
between physical ports, interfaces, and zones. The following illustration provides an overview 
of the relationship between physical ports, interfaces, and zones in the ZyWALL. It also 
identifies the types of features you can configure with each one.
