Problems With LAN Game Announcements and Broadcasts on Windows 7

On Windows 7 users trying to use LAN games, Bonjour/mDNS, or other broadcast or multicast protocols may have problems with those protocols announcing over ZeroTier networks. This is a known Windows 7 issue, and a work-around is documented on Microsoft Technet.

There is also a small open source utility called WinIPBroadcast available that assists by relaying broadcasts between interfaces.
