My strong recommendation is to first get everything working reliably amongst NAT pairs that don’t require port prediction (ie, everything but symmetric/symmetric and symmetric/restricted-cone). That alone is an enormous amount of really exciting work. Once you have been able to achieve something like 90% peer connectivity with acceptable connection setup time, then I’d ask: do you really, seriously need the remaining 10%? But regardless of the answer to that question, you shouldn’t even ask it until you’ve already got the “basics” solidly down. -david From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Syzygy Dc Sent: Thursday, November 08, 2007 1:12 AM To: [email protected] Subject: [p2p-hackers] udp nat traversal I am implementing udp nat traversal project and need to know how to do port prediction. Can anyone provide me links to good literature on nat traversal and advise from anyone experienced with nat traversal?
