Inbound 
kbps
Type how much inbound bandwidth, in kilobits per second, this policy 
allows the traffic 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 matching 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.
Outbound 
kbps
Type how much outbound bandwidth, in kilobits per second, this policy 
allows the traffic 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 matching 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.
Priority
This field displays when the inbound or outbound bandwidth 
management is not set to 0. Enter a number between 1 and 7 to set the 
priority for traffic that matches this policy. The smaller the number, the 
higher the priority. 
Traffic with a higher priority is given bandwidth before traffic with a 
lower priority. 
The ZyWALL uses a fairness-based (round-robin) scheduler to divide 
bandwidth between traffic flows 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.
Maximize 
Bandwidth 
Usage
This field displays when the inbound or outbound bandwidth 
management is not set to 0. Enable maximize bandwidth usage to let 
the traffic matching this policy “borrow” any unused bandwidth on the 
out-going interface. 
After each application or type of traffic gets its configured bandwidth 
rate, the ZyWALL uses the fairness- based scheduler to divide any 
unused bandwidth on the out-going interface amongst applications and 
traffic types that need more bandwidth and have maximize bandwidth 
usage enabled.
Log
This field controls what kind of record the ZyWALL creates when traffic 
matches this policy. See 
 for more on logs.
no - the ZyWALL does not record anything
log - the ZyWALL creates a record in the log
log alert - the ZyWALL creates an alert
