Packet Filtering

Note:

This mode should be used when the VSU is dedicated to VPN traffic and is in parallel with another device (such as a router or firewall) that can resolve ARPs from the private network to the Internet gateway. This mode should not be used when the VSU is the only path between network devices and a router with which those devices need to communicate.

Drop all fragments - When checked, discards all non-expected IP packet fragments. Normally used to prevent tiny fragment attacks (RFC1858).

Drop all short packets - When checked, this function drops all packets that are not a valid size.

Keep filter statistics (SNMP) - When checked, statistics for this filter are reported via SNMP.

Memo - Use this area to record comments or notes about your filter.

Add Packet Filtering Policy

This screen performs two basic functions, selection of the desired action, and selection of the traffic type for which a filter is constructed. Additional buttons are provided for Advanced functions, Close, Next, and Finished

Action - Two basic actions may be selected: Permit, or Deny. As you would expect, Permit allows all packets of the Traffic type selected to pass, while Deny blocks all packets of the Traffic type selected.

QoS Mark - QoS Mark is a drop-down menu of choices used when differentiated levels of priority IP packet routing is used. This allows Quality of Service markings to be placed in the outer IP header when applying the IPSec tunnel mode, thereby allowing “QoS-aware” devices within an MPLS cloud to maintain the desired level of priority in handling the packets. Packets to be marked at the VSU are indicated further specification in the filtering criteria.

A comprehensive list of QoS preset markers are provided in the drop-down menu. For information on the use of these markers, or constructing user defined markers, please refer to the following for details.

●RFC 2474: Definition of the Differentiated Services Field (DS Field) in the IPv4 and IPv6 Headers (http://www.ietf.org/rfc/rfc2474.txt?number=2474)

●RFC 2598: An Expedited Forwarding PHB (http://www.ietf.org/rfc/ rfc2598.txt?number=2598)

●You may also wish to check out (http://www.ietf.org/html.charters/diffserv-charter.html) which contains a set of links to relevant related RFC's including 2497 and 2598.
