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.

application.

messages.

Bandwidth
Management
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.
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.
