Keith, it seems that you are describing ICE. Of course, ICE only really works for UDP based applications. So we may need to run TCP or a new equivalent protocol on top of UDP. Of course, if we do that, we can also get a solution that works through not only NAT, but also basic stateful firewalls. ICE, STUN, TURN forever. Not exactly what we were shooting for in 1992. Oh well. -- Christian Huitema _______________________________________________ nat66 mailing list [email protected] https://www.ietf.org/mailman/listinfo/nat66
