About bandwidth control
You can create classes of service that guarantee or restrict bandwidth allocation to a specific IP address, or groups of IP addresses. Classes can offer a “best efforts” bandwidth allocation. You can create classes to guarantee a minimum bandwidth allocation available for specific applications, restrict specific applications to a maximum bandwidth allocation and equally reduce the quality of service within a class of service group.
Note: Traffic to and from the Smoothwall’s administration user interface, User Portal, and SSH traffic to the Smoothwall, isn't limited, as an error in configuration might prevent access.
