>Description:
For systems which use ipfilter, after inserting an interface it is
necessary to run 'ipf -y' to resync its interface list.
For example,
pass in quick on wi0 from ....
block in log all
where wi0 is a pcmcia card: after a reboot all traffic is
blackholed until you issue 'ipf -y'. It took me a while to work
this out, since 'log' shows the packets being blocked even though
they obviously match rules which should let them in :-)
>How-To-Repeat:
>Fix:
I suggest a few lines are added to /etc/pccard_ether based on what
rc.network does after adding ppp interfaces:
.. set ipfilter_active if either ipfilter_enable or ipnat_enable=YES
case ${ipfilter_active} in
[Yy][Ee][Ss])
${ipfilter_program:-/sbin/ipf} -y ${ipfilter_flags} >/dev/null
