"""
|
|
Doing this the "right" way by using DIOCNATLOOK on the pf device turns out
|
|
to be a pain. Apple has made a number of modifications to the data
|
|
structures returned, and compiling userspace tools to test and work with
|
|
this turns out to be a pain in the ass. Parsing pfctl output is short,
|
|
simple, and works.
|
|
|
|
Note: Also Tested with FreeBSD 10 pkgng Python 2.7.x.
|
|
Should work almost exactly as on Mac OS X and except with some changes to
|
|
the output processing of pfctl (see pf.py).
