Yes, this sounds logical, but many NAT routers will rewrite the source port, and the scheme you outlined relies on the fact that the parts are sending to the correct ports which will be opened for a brief window of time (45 seconds is default in Linux at least). In the cases where the source port have been changed by the router, the clients have no way of knowing which port to send to, thus communication cannot be established. I suspect this happens more frequently on routers when there is high amounts of traffic going on.-----Original Message----- From:
Well the question is whether they (the NAT's) close the window after 45 seconds from the first packet, or the 'last' packet, since a timeout of a silent p2p channel can be 5 seconds with no problem, just go again if needed. I think the timeout is even smaller in DC today.
