SECURITY > FILTERS > INTERFACES

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

SECURITY > FILTERS > FILTER DEFINES menu, and

2) set up the filter type and combination of defines that will cause a packet block.

SECURITY > FILTERS > INTERFACES (T1[0])

Define the filters for the T1 interfaces from this menu.

SECURITY > FILTERS > INTERFACES (T1[0]) > SUB-INTERFACE

If the L2 PROTOCOL is FRAME RELAY, the SUB-INTERFACE will be FRE [0.X], where the [0.X] represents the

T1 physical and logical ports respectively. The T1 physical port is always zero. The X represents the Frame

Relay logical port and will always be a number 0-9 corresponding to the interface number under

ROTOCOL > CONFIG > DLCI MAPPING. This is a read-only field.

If the

L2 PROTOCOL is PPP, the SUB-INTERFACE is PPP [0.0]. The [0.0] represents the T1 physical and

logical ports respectively. This is a read-only field.

SECURITY > FILTERS > INTERFACES (T1[0]) > SET-UP

Enable the T1 interface filtering and define filters from this menu.

TCP ESTAB

Ye s - only when TCP established

Ignore - ignore TCP flags (default)

The T1 interface will only appear in the SECURITY > FILTERS > INTERFACE list if the L2

PROTOCOL is set to FRAME RELAY or PPP.

The packets which come into the unit can be filtered in three ways:
