Sender IP 0.0.0.0
NetDefendOS can be configured on what to do with ARP queries that have a sender IP of 0.0.0.0.
Such sender IPs are never valid in responses, but network units that have not yet learned of their IP
address sometimes ask ARP questions with an "unspecified" sender IP. Normally, these ARP replies
are dropped and logged, but the behavior can be changed by modifying the Advanced Setting
ARPQueryNoSenderIP.
Matching Ethernet Addresses
By default, NetDefendOS will require that the sender address at Ethernet level should comply with
the Ethernet address reported in the ARP data. If this is not the case, the reply will be dropped and
logged. Change the behavior by modifying the Advanced Setting ARPMatchEnetSender.
