Put it simply: NAT Loopback.

举例说:

              C
         65.102.10.35
              |
              |
              |
         65.102.10.34
          R(router)
         192.168.1.1     
          /      \
         /        \
        /          \
       /            \
      A              B
192.168.1.2    192.168.1.3

当A和B都和公网上的机器通信(比如说C)时, 路由器会给A和B做NAT, 比如说A(65.102.10.34:8888), B(65.102.10.34:9999).

当A给65.102.10.34:9999发包时, 路由器的公网port会loopback. 此为hairpin.
