The default configuration of the Solaris 10 OS has packet filtering disabled on all network interfaces. To enable packet filtering on the hme0 interface of a running system, the
related hme line in the /etc/ipf/pfil.ap file must be uncommented:
# IP Filter pfil autopush setup
#
# See autopush(1M) manpage for more information.
#
# Format of the entries in this file is:
#
#major minor lastminor modules
#le -1 0 pfil
#qe -1 0 pfil
hme -1 0 pfil
#qfe -1 0 pfil
