Examples of Bandwidth Management Rules
Enabling Bandwidth Management on the SonicWALL
To enable Bandwidth Management on the SonicWALL, you must know the current bandwidth of
your connection. Once you have this figure, you can select
Enable Bandwidth Management
on the
Advanced/Ethernet
page, and then enter the amount of available WAN bandwidth in
Kbps. Now that you have enabled Bandwidth Management, you can begin configuring Rules to
use bandwidth management.
Note
: Traffic inbound from the WAN to the LAN based on a Rule using bandwidth management
is allowed as if there is no bandwidth management in place. However, outbound traffic (reply
packets) for traffic associated with an inbound Rule is managed based on the configuration for
that Rule.
MTU Settings
A network administrator may set the
MTU
(Maximum Transmission Unit) allowed over a packet
or frame-based network such as TCP/IP. If the MTU size is too large, it may require more
transmissions if the packet encounters a router unable to handle a larger packet. If the packet
size is too small, this could result in more packet header overhead and more acknowledgements
that have to sent and processed.
The default value is 1500 octets based on the Ethernet standard MTU. The minimum value that
can be set is 68. Decreasing the packet size may improve the performance of the network.
