Overview In P2P communication, problems caused by NAT (Network Address Translation) are well known, it causes the P2P client inside the NAT to be inaccessible regardless of the valid public IP address. AlthoughHowever, a variety of NAT traversal technologies have been developed, but there are few technical documents to prove the stability and advantages of these technologies. The purpose of this article i
