HTTP traffic needs to be given priority over FTP traffic.
FTP traffic from the WAN to the DMZ must be limited so it does not interfere
with SIP and HTTP traffic.
FTP traffic from the LAN1 to the DMZ can use more bandwidth since the
interfaces support up to 1 Gbps connections, but it must be the lowest priority
and limited so it does not interfere with SIP and HTTP traffic.
Figure 270 Application Patrol Bandwidth Management Example
28.1.3.1 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.
28.1.3.2 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.
