ZyWALL USG 300 User’s Guide

If a packet matches a signature, the action specified by the signature is taken. You can change 
the default signature actions in the profile screens. 

A zone is a combination of ZyWALL interfaces and VPN connections for security. See the 
zone chapter for details on zones and the interfaces chapter for details on interfaces. Traffic 
direction is defined by the zone the traffic is coming from and the zone the traffic is going to.

An IDP profile is a set of IDP rules with configured activation, log and action settings. The 
ZyWALL comes with default profiles that you can bind to traffic directions. For example, by 
default, the default LAN_IDP profile is bound to any traffic going to the LAN zone. You 
could use this to protect your LAN computers. 

You can also create your own IDP profiles from base profiles. See 

 for 

details on base profiles.

"

You can only bind one profile to one traffic direction.

Click Anti-X > IDP > General to open this screen. Use this screen to turn IDP on or off, bind 
IDP profiles to traffic directions, and view registration and signature information.

You must register in order to use packet inspection signatures. See the 
Registration screens. 

If you try to enable IDP when the IDP service has not yet been registered, a warning screen 
displays and IDP is not enabled.
