Figure 357 Application Patrol Bandwidth Management Example
27.1.3.1 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.
27.1.3.2 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.
