Computer A and game server 1 are connected to each other until the connection 
is closed or times out. Any other computers (such as or C) cannot connect to 
remote server using the same port triggering rule as computer A unless they 
are using a different next hop (gateway, outgoing interface, VPN tunnel or trunk) 
from computer A or until the connection is closed or times out.

Maximize Bandwidth Usage
The maximize bandwidth usage option allows the ZyWALL to divide up any 
available bandwidth on the interface (including unallocated bandwidth and any 
allocated bandwidth that a policy route is not using) among the policy routes that 
require more bandwidth. 
When you enable maximize bandwidth usage, the ZyWALL first makes sure that 
each policy route gets up to its bandwidth allotment. Next, the ZyWALL divides up 
an interface’s available bandwidth (bandwidth that is unbudgeted or unused by 
the policy routes) depending on how many policy routes require more bandwidth 
and on their priority levels. When only one policy route requires more bandwidth, 
the ZyWALL gives the extra bandwidth to that policy route. 
When multiple policy routes require more bandwidth, the ZyWALL gives the 
highest priority policy routes the available bandwidth first (as much as they 
require, if there is enough available bandwidth), and then to lower priority policy 
routes if there is still bandwidth available. The ZyWALL distributes the available 
bandwidth equally among policy routes with the same priority level.
