parpd is a Proxy ARP Daemon and complies with RFC 1027. parpd is released under the 2 clause BSD license.
Configuration is found in the file /etc/parpd.conf
Comment lines should start with # or ;
Each line compromises of two or three words:
<command> <inet address> [<hardware address>]
Here are some examples:
# parpd.conf example
# These two do the same thing
proxy 192.168.0.0/24
proxy 192.168.0.0/255.255.255.0
# Send this hardware address to this host
proxy 192.168.0.5 aa:bb:cc:dd:ee:ff
# Ignore a host
ignore 192.168.0.8
# another parpd.conf example
# This one is more interesting - it tells parpd to proxy all ARP requests
# except for a specific subnet.
proxy 0.0.0.0
ignore 10.0.0.0/24
