8-8 Filter Configuration

Applying a Filter Set

After conﬁguring a ﬁlter set in Menu 21, you must specify where and how the ﬁlter will be used.

Data ﬁlters can be applied either at the LAN interface (in Menu 3.1) or at the Remote Node

interface (Menu 11.1) and can be speciﬁed for incoming or outgoing packets. Call ﬁlters, which

determine whether or not to place a call to forward the packet, are applied at the Remote Node

interface (Menu 11.1). Up to four ﬁlter sets can be applied to the same port by entering the

numbers of the desired ﬁlter sets, separated by commas, with no spaces. In the following example,

the Remote Node Proﬁle line of Menu 11.1 speciﬁes that ﬁlter sets 1, 3, and 10 are used to

determine whether a packet causes a call to be placed to the Remote Node.

Call Filter Sets = 1,3,10
