flush states pfctl

[joostvgh]

hi

I am currently using scripts to load a daypf.conf and nightpf.conf
at night people are allowed to use torrents etc.

so when I enable daypf.conf I would like to flush all connections made (connections to trackers etc although they are not allowed by new pf.conf)

question:
do the states get flushed by disabling and enabling pfctl with another pf.conf?

I googled this and read man page:

pfctl -F all
when I do this, pfctl clears all states but my putty console hangs. this is probably due to my state being flushed too.

my script:
pfctl -d
pfctl -F all
pfctl -e -f /etc/pf.conf

is this the correct way to do it?
