1740 SHDSL 2/4-Wire Router User’s Guide
CHAPTER 6 Packet Filter
Packet filter, a firewall security measure, examines incoming and outgoing packet headers (IP address,
port number, and so on) on the network and determines whether to forward the packets based on user-
defined rules (deny, accept, and count).
The SHDSL router provides packet filter and stateful packet inspection. It has denial of service protection
against attacks such as ICMP Flood, Ping of Death, IP spoofing, Port Scans, Land Attacks, Tear Drop
Attacks, IP Source Route and WinNuke Attacks.
To access the packet filter functions, select PFilter from the advanced menu. The screen will display as
below, showing a list of the currently configured filter entries.
