Figure 2 Managing the Bandwidth of VPN traffic between hosts
How you configure this command affects how you can implement bandwidth management as
follows.
• Leave this command set to
off to be able to create bandwidth management groups for
individual unencrypted VPN traffic that are connecting through the same remote IPSec
router. With this setting you can also specify the type of traffic either using the service list
(like SIP or FTP) or by specifying port numbers in BWM filter settings.
•Use off with this command to set the ZyWALL uses the source and destination IP
addresses of unencrypted VPN packets in managing the bandwidth of the VPN traffic.
This means that it looks at the IP address of the computer that sent the packets and the IP
address of the computer to which it is sending the packets. The following figure shows an
example of this. The ZyWALL uses the IP addresses of computers A and B to manage the
bandwidth of the VPN traffic.
6.3 Command Examples
This example displays the LAN interface’s BWM settings and then configures the LAN
interface using bandwidth 10,000 bps and the priority-based queuing method.
This example adds one LAN class using following settings.
• Class number: 1
• Bandwidth: 5,000,000 bps
• Class Name: LAN-class1
