Does the "p2p-friendly" mean the NAT allows the STUN messages pass through? How does the message 1 (STUN) go through the NAT? I guess the TURN server has to send STUN keep alive messages to keep the NAT hole open before the TURN request expire? thanks, Jerry _______________________________________________ P2PSIP mailing list [EMAIL PROTECTED] https://www1.ietf.org/mailman/listinfo/p2psip
