Subject: "Listenless" TCP over NAT?
Date: Fri, 05 Sep 2008 13:45:13 +0200 [thread overview]
Message-ID: <WorldClient-F200809051345.AA45130148@butn.net> (raw)
Hi!
Recently someone mentioned on this (or maybe other...) list a seldom used
technique of establishing a TCP connection without one host listening on a port,
but but acting as "clients" and connecting to the peers port.
My question: Can this be used to establish a TCP connection between two hosts that
are both behind a (P)NAT router ?
(the idea being: NAT router lets outgoing connections thru, and in this case both
NAT router would see an "outgoing" connection)
If yes, this would simplify the life of many users :-)
Regards,
David
