Chapter 27 Application Patrol

Table 115 Application Policy Edit (continued)

LABEL	DESCRIPTION
Schedule	Select a schedule that defines when the policy applies or select Create Object to
	configure a new one (see Chapter 37 on page 527 for details). Otherwise, select
	none to make the policy always effective.
User	Select a user name or user group to which to apply the policy. Select Create
	Object to configure a new user account (see Section 34.2.1 on page 506 for
	details). Select any to apply the policy for every user.
From	Select the source zone of the traffic to which this policy applies.
To	Select the destination zone of the traffic to which this policy applies.
Source	Select a source address or address group for whom this policy applies. Select
	Create Object to configure a new one. Select any if the policy is effective for every
	source.
Destination	Select a destination address or address group for whom this policy applies. Select
	Create Object to configure a new one. Select any if the policy is effective for every
	destination.
Access	This field controls what the ZyWALL does with packets for this application that
	match this policy. Choices are:
	forward - the ZyWALL routes the packets for this application.
	Drop - the ZyWALL does not route the packets for this application and does not
	notify the client of its decision.
	Reject - the ZyWALL does not route the packets for this application and notifies the
	client of its decision.
Action Block	For some applications, you can select individual uses of the application that the
	policy will have the ZyWALL block. These fields only apply when Access is set to
	forward.
	Login - Select this option to block users from logging in to a server for this
	application.
	Message - Select this option to block users from sending or receiving instant
	messages.
	Audio - Select this option to block users from sending or receiving audio traffic.
	Video - Select this option to block users from sending or receiving video traffic.
	File Transfer - Select this option to block users from sending or receiving files.
Bandwidth	Configure these fields to set the amount of bandwidth the application can use.
Management	These fields only apply when Access is set to forward.
	You must also enable bandwidth management in the main application patrol screen
	(AppPatrol > General) in order to apply bandwidth shaping.
Inbound kbps	Type how much inbound bandwidth, in kilobits per second, this policy allows the
	application to use. Inbound refers to the traffic the ZyWALL sends to a
	connection’s initiator.
	If you enter 0 here, this policy does not apply bandwidth management for the
	application’s traffic that the ZyWALL sends to the initiator. Traffic with bandwidth
	management disabled (inbound and outbound are both set to 0) is automatically
	treated as the lowest priority (7).
	If the sum of the bandwidths for routes using the same next hop is higher than the
	actual transmission speed, lower priority traffic may not be sent if higher priority
	traffic uses all of the actual bandwidth.
