29.1.3.1 Setting the Interface's Bandwidth
Use the interface screens to set the WAN zone interface's upstream bandwidth to
be equal to (or slightly less than) what the connected device can support. This
example uses 1000 Kbps.

29.1.3.2 SIP Any to WAN Bandwidth Management Example

• Manage SIP traffic going to the WAN zone from a VIP user on the LAN or DMZ.
• Outbound traffic (to the WAN from the LAN and DMZ) is limited to 200 kbps.
The ZyWALL applies this limit before sending the traffic to the WAN.
• Inbound traffic (to the LAN and DMZ from the WAN) is also limited to 200 kbps.
The ZyWALL applies this limit before sending the traffic to LAN or DMZ.
• Highest priority (1). Set policies for other applications to lower priorities so the
SIP traffic always gets the best treatment.
• Enable maximize bandwidth usage so the SIP traffic can borrow unused
bandwidth.

29.1.3.3 SIP WAN to Any Bandwidth Management Example

You also create a policy for calls coming in from the SIP server on the WAN. It is
the same as the SIP Any to WAN policy, but with the directions reversed (WAN to
Any instead of Any to WAN).

29.1.3.4 HTTP Any to WAN Bandwidth Management Example

• Inbound traffic gets more bandwidth as the local users will probably download
more than they upload (and the ADSL connection supports this).
• Second highest priority (2). Set policies for other applications (except SIP) to
lower priorities so the local users' HTTP traffic gets sent before non-SIP traffic.
