Isn't there a way to tell a firewall to allow dynamic port allocation ? I believe my Cisco E4200 wireless router has this option. Is there a section of ports that is allowed for just this sort of thing ?
Sure. I wrote and submitted a netfilter connection tracking module for UPNP discovery back in February. You can find it on the netfilter-devel list.
Unfortunately, the powers that be were totally uninterested, because they're working on a framework to move all such connection tracking to user-space. Of course, said framework doesn't appear to have seen the light of day yet. :-(
