In most cases STUN ( simple traversal of UDP through network address translators ) can afford successful solutions for NAT traversal . But in symmetric NAT case STUN can not accomplish NAT traversal .

According to the dynamic and statistical characteristics of symmetric NAT PS-STUN do symmetric NAT traversal by using forecasting technology based on measurement and scanning methods .
