Figure 358 SIP Any to WAN Bandwidth Management Example
27.1.3.3 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).
27.1.3.4 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.
• Enable maximize bandwidth usage so the HTTP traffic can borrow unused bandwidth.

27.1.3.5 FTP WAN to DMZ Bandwidth Management Example
• ADSL supports more downstream than upstream so you allow remote users 300 kbps for
uploads to the DMZ FTP server (outbound) but only 100 kbps for downloads (inbound).
• Third highest priority (3).
• Disable maximize bandwidth usage since you do not want to give FTP more bandwidth.
Inbound: 200 kbps
Outbound: 200 kbps
