Blocking Specific Protocols

The Blocked Protocols feature enables you to prevent the HM210dp/di from
passing any data that uses a particular protocol. Unlike the IP Filter feature,
you cannot specify additional criteria for blocked protocols, such as
particular users or destinations.

NOTE! Blocking certain protocols may disrupt or disable your
network communication or Internet access. DO NOT use this
feature unless you are certain that a particular protocol is not

needed or wanted on your network.
