miniupnp port for FreeBSD-PF

[Scott Ullrich]

Hello!

Thanks to Seth Mos of the pfSense project and http://miniupnp.free.fr/
we would like to present the first draft of a enhanced miniupnpd port.

This ports extends the version found http://miniupnp.free.fr/ to
automatically install pf rules for the opened upnp rdr ports.  In
addition I have added a -o switch allowing a user to override the wan
ip so that CARP can work correctly.

The port skeleton can be found at
http://www.pfsense.com/~sullrich/ports/net/miniupnpd.tgz ... Simply
extract it to /usr/ports/net/

To start miniupnpd simply run something similar to this:

miniupnpd -i fxp0 -a 10.0.250.2 -o X.X.X.X -p 2689

-i  = wan interface
-a = lan ip to listen on
-o = desired wan ip to listen on (optional)
-p = port to listen on

Things that need to be done still:

 * Manual page

Thanks to Andrew Thompson for helping me with the -o option when I was
having brain issues and to Seth Mos for adding the additional firewall
rule support.   Also thanks  to Thomas Bernard who created miniupnpd.

Comments, questions, please!
