If you use VoIP and NetMeeting at the same time, the device allocates up to 500 Kbps of
bandwidth to each of them before it allocates any bandwidth to FTP. As a result, FTP can only
use bandwidth when VoIP and NetMeeting do not use all of their allocated bandwidth.
Suppose you try to browse the web too. In this case, VoIP, NetMeeting and FTP all have
higher priority, so they get to use the bandwidth first. You can only browse the web when
VoIP, NetMeeting, and FTP do not use all 1000 Kbps of available bandwidth.

DESCRIPTION
These read-only labels represent the physical interfaces. Select an interface's check
box to enable bandwidth management on that interface. Bandwidth management
applies to all traffic flowing out of the router through the interface, regardless of the
traffic's source.
Traffic redirect or IP alias may cause LAN-to-LAN or DMZ-to-DMZ traffic to pass
through the ZyWALL and be managed by bandwidth management.
Select an interface's check box to enable bandwidth management on that interface.
Enter the amount of bandwidth for this interface that you want to allocate using
bandwidth management. This appears as the bandwidth budget of the interface's
root class (see Section 19.12 on page
The recommendation is to set this speed to match the interface's actual
transmission speed. For example, set the WAN interface speed to 1000 kbps if your
Internet connection has an upstream transmission speed of 1 Mbps.
You can set this number higher than the interface's actual transmission speed. This
will stop lower priority traffic from being sent if higher priority traffic uses all of the
actual bandwidth.
You can also set this number lower than the interface's actual transmission speed. If
you do not enable Maximize Bandwidth Usage, this will cause the ZyWALL to not
use some of the interface's available bandwidth.
