Comment (by yawning):

 Pushed more changes.  Most notable is that NAT-PMP should work on all of
 the BSDs assuming that it's possible to dump the routing table via sysctl.
 I tested the code on FreeBSD 9.3-p3, so I'm fairly confident it works on
 Darwin, which is the main driving factor behind even supporting that OS in
 the first place.

 TODO:
  * Windows implementation of `getGateway()`.
  * Shed a single tear as no one does the deployment side, this codebase
 gets forgotten and we are still without a firewall helper.

 I'll do the Windows part today sometime.  Go figure the Windows box I
 acquired out of a bin for $100 is a bit on the slow side, and updating the
 OS has taken all night so far.  It should take longer to get a Go compiler
 and MinGW on the thing than it will to write and debug the code.
