Per Server Quota
This option allows you to safeguard your servers
from coordinated denial-of-service attacks from
any client to any single server. After clicking this
checkbox, enter a threshold number in the text
field that represents the maximum request
capacity (per second) of that server. If there are
more than the specified number of connection
requests within a second, the Firebox Vclass
appliance will drop the excess requests within that
same second. This will protect your server from
being overwhelmed by too many connection
requests in a short period of time.
Per Client Quota
Use this option to restrict the number of
connection requests from a single client within a
second. After clicking this checkbox, enter a
threshold number in the text field that represents
the maximum number of requests (per second)
from a single client. If there are more than the
specified number of connection requests within a
second, the Firebox Vclass appliance will drop the
excess requests within that same second.
