Use the
IP Filter Table
to specify up to 60 specific filtering actions and also to designate a default IP action
for frames not matching any filter specification. The IP Filter process searches from the top of the table
(after a sort process described below) and performs a filtering action based on the first match that it finds for
an address. If no match is found for either the source or destination address, the call is blocked or forwarded
based on the selection in the
Default filter action
field. This field is initially configured to forward all
traffic.
