+MIPCFF, Control Filtering Feature for Incoming TCP Connection
The filtering feature aims to protect the G24-L from non-authorized clients trying to establish an 
IP connection with it. It is applicable for cases where G24-L communicates as a listener with 
others devices.
The filtering feature consists of a "white list" defined per connection.  The "white list" can be 
configured when filtering feature is set to disable and before connection is established. Once a 
connection is established, changes in its "white list" are forbidden.
The following services are provided by the G24-L on behalf the "white list" management:
Disable/Enable filtering on a connection;
Add/Remove IP to/from "white list";
Clear "white list"
After Power-up, the "white list" will be empty and disabled for all connections.

A 1 bits.
