The unit can block packets in and out of an interface by use of the filters. They are set up in two steps: 1)
define the types of packets that would be of interest in the
S ECURITY > F ILTERS > F ILTER D EFINES
menu, and
2) set up the filter type and combination of defines that will cause a packet block.

This is a read-only field which displays the physical and logical port of the interface using the following
nomenclature: [A.B], where A represents the physical port (network interface is 0, Ethernet is 1) and B
represents the logical port for the Layer 2 protocol (i.e. PVC for Frame Relay, PPP link, etc.) Each
configured logical port is assigned a number corresponding to the order in which they are listed in the L2
Protocol configuration fields.
D EST P ORT C OMP
Type of comparison that is performed. Default is N ONE
.
= means ports equal to
NOT = means port not equal to
> means port greater than
< means port less than
None - means the source port is not compared
P ROTOCOL
Protocol used for comparison. Value is in decimal format. Range: 0 - 255 . Default is 0 .
