DESCRIPTION
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.
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.
Configure these fields to set the amount of bandwidth the application can use.
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.
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.
Type how much outbound bandwidth, in kilobits per second, this policy allows the
application to use. Outbound refers to the traffic the ZyWALL sends out from 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 out from 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.
Enter a number between 1 and 7 to set the priority for this application's traffic that
matches this policy. The smaller the number, the higher the priority.
The ZyWALL gives traffic of an application with higher priority bandwidth before
traffic of an application with lower priority.
The ZyWALL uses a fairness-based (round-robin) scheduler to divide bandwidth
between applications with the same priority.
The number in this field is ignored if the incoming and outgoing limits are both set to
0. In this case the traffic is automatically treated as being set to the lowest priority
(7) regardless of this field's configuration.
