The IP Filter parameters are described below:
•
Name – This is a 12 character (maximum), alphanumeric, user-
defined name, used to identify the filter.
•
Direction – This defines the direction of the packet relative to the
Interface parameter below.
•
State – This is used to define the routing decision applied to the
packet. The three routing decisions are described:
1. forward – This allows the routing of the packet, if it has met the
criteria of the corresponding filter.
2. drop – This drops (doesn’t allow routing for) a specific packet
that has met the criteria of the corresponding filter.
3. disable – This does not apply the IP filter.
•
Interface – This applies the filter to a specific interface, LAN or
one of the ISDN interfaces.
•
Protocol Type – This is a protocol identifier, as assigned by the
Internet Assigned Numbers Authority (IANA). The values of this
identifier are described in RFC-1700. This router supports the
following:
1 – This is Internet Control Message (ICMP), defined in RFC 792.
6 – This is Transmission Control (TCP), defined in RFC 793.
17 – This is User Datagram (UDP), defined in RFC 798.
