Blocked Protocols
The [Blocked Protocols] feature enables you to prevent the ADSL
Barricade 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.
However, when you are certain that a particular protocol is not
needed or wanted on your network, this feature provides a
convenient way to discard such data before it is passed.
To display the [Blocked Protocols] page, click the [Services] tab,
and then click [Blocked Protocols] in the task bar. The [Blocked
Protocols] page appears, as shown in Figure 52.

Warning: Blocking certain protocols may disrupt or
disable
your network communication or Internet
access.
If you are unfamiliar with how your network
or Internet connection uses these protocols,
contact your ISP before disabling.
