I just added net-misc/minissdpd to the tree. This is a helper to miniupnpc and miniupnpd as described on the home page: http://miniupnp.free.fr/minissdpd.html It helps speed up device discovery. However, it should before either of these. I've already added depend() { need net before miniupnpd } to the init script of minissdpd. It would be useful if miniupnpd's init script had depend() { need net iptables use minissdpd } So it can make use of it, if it is available.
Fixed :)
