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. Se
 for more on logs.
