27.10 Other Protocol Screen
The Other Protocol screen controls the default policy for TCP and UDP traffic that the
ZyWALL cannot identify. In other words, you can control what the ZyWALL does when it
does not recognize the application. This screen also allows you to add, edit, and remove
conditions to this default policy.

Outbound
kbps
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.
Priority 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.
Maximize
Bandwidth
Usage
Enable maximize bandwidth usage to let the traffic matching this policy “borrow”
any unused bandwidth on the out-going interface.
After each application gets its configured bandwidth rate, the ZyWALL uses the
fairness- based scheduler to divide any unused bandwidth on the out-going
interface amongst applications that need more bandwidth and have maximize
bandwidth usage enabled.
Log Select whether to have the ZyWALL generate a log (log), log and alert (log alert)
or neither (no) when the application’s traffic matches this policy. See Chapter 46 on
page 625 for more on logs.
