[zeromq-dev] Hole Punching
Hi all, I'm developing P2P application using zeromq. In the real world, some peers are visible to others (they have public IP), some peers are invisible to others as they behind a NAT. The paper Peer-to-Peer Communication Across Network Address Translators ( http://www.brynosaurus.com/pub/net/p2pnat/) shows how to make connection between peers behind NAT devices. I tried to apply this, and I can make this happen with regular socket but I don't know how to do with zeromq. Could you please give me some advice for this issue? -- Thanks and Best Regards, Ngo Doan Lap Mobile: 0977.833.757 ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org http://lists.zeromq.org/mailman/listinfo/zeromq-dev
Re: [zeromq-dev] Peer to peer connection
Thank for your answer,Ahmet Kakıcı Each peer will use other's public ip address to connect but you have to forward ports to internal ip adresses. A will connect to tcp://87.96.124.16: or bind to tcp://*:. B will connect to tcp:173.169.213.16: or bind to tcp://*:. You both have to forward port to A's and B's internal ip:port pairs. By using a centerlized server (have public IP) we can know public IP, private IP and internal ports of A and B. but the issues is how do we know external port by using zeromq?
