What "ipac~i" means may be subject to opinion (though I also think
it's very confusing). But regardless, the default rules.conf is
inconsistent. Consider this case:

# Format:
# Name of rule|direction|interface|protocol|source|destination

#                       ipac~i   - outgoing from machine with ipac-ng to other 
host(/net)
#                                       (or incoming to otherhost)

#
# connections from this machine to ...
#
# http (port 80)
tonet in http|ipac~i|+|tcp|0/0 80|0/0

So "tonet in http" is "ipac~i" which means outgoing from the
machine. And it's source port 80. So it's connections going from
this machine's port 80 to somewhere, which usually means replies to
HTTP requests (which makes up the bulk of the traffic on typical web
servers, as confirmed by the actual numbers of our server).

But the comment says "connections from this machine to ...", which
is wrong, as it's actually replies to connections *to* this machine.

And the label "tonet in http" is also wrong (or at least, very
confusing). AFAICS, it should be "tomachine out http".
