• Inbound and outbound traffic are both guaranteed 1000 kbps and limited to 2000 kbps.

In the Configuration > BWM screen, click Add.
1
In the Add Policy screen, select Enable and type SIP Any-to-WAN as the policy's name.
2
Leave the incoming interface to any and select wan1 as the outgoing interface.
Select App Patrol Service and sip as the service type.
Set the inbound and outbound guaranteed bandwidth to 1000 (kbps) and maximum bandwidth to
2000 kbps and priority 1. Click OK.
Note: Use App Patrol Service for the services classified by the USG's IDP packet
inspection signatures. Use Service Object for pre-defined services.
2 Repeat the steps above to create another policy named SIP WAN-to-Any 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).
4.1.5 HTTP Any-to-WAN Bandwidth Management Example
• Set inbound guaranteed and maximum rates as the local users on the LAN and DMZ will probably
download more than they upload to the Internet.
• Set fourth highest priority (4) for the HTTP traffic in both directions.
