+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.

White List	List of IP addressed that represent devices which
	are allowed to establish an IP connection with
	G24-L. The white list is defined per connection.
Listen Mode	A mode in which the G24-L expects to received
	data from the other side.
IP CIDR	An efficient way to represent range of
	IP_Addresses. It composed of "IPaddr/A", where:
	IP_address's format is "AAA.BBB.CCC.DDD",
	/A indicates that the subnet mask would start with
	A 1 bits.
	See Figure 3-16.
