Ok, put that code back and then remove the line that says: if (setsockopt(fd, SOL_SOCKET, SO_ATTACH_FILTER ... and the following line with the goto and see what that does.
It also fixes the problem; I can host a game in multiplayer mode, and cast spell/attack entities.
Can you double check that when you add this part back in that it breaks your application? It sounds like, for some reason, the incoming packet filter isn't working properly for your application.
