Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

go version go1.9.2 linux/amd64

What did you do?

Server side:

ServerAddr,err := net.ResolveUDPAddr("udp",":11110")
ServerConn, err := net.ListenUDP("udp", ServerAddr)
n,addr,err := ServerConn.ReadFromUDP(buf)
fmt.Println("Received ",string(buf[0:n]), " from ",addr, " to ", ServerConn.LocalAddr())

Client side:

ServerAddr1,err := net.ResolveUDPAddr("udp", "10.16.83.185:11110")
Conn1, err := net.DialUDP("udp", nil, ServerAddr1)
_,err := Conn1.Write(buf)

ServerAddr2,err := net.ResolveUDPAddr("udp", "127.0.0.1:11110")
Conn2, err := net.DialUDP("udp", nil, ServerAddr2)
_,err := Conn1.Write(buf)

What did you expect to see?

Received  1  from  10.16.83.185:51386  to  10.16.83.185:11110
Received  1  from  127.0.0.1:58306  to  127.0.0.1:11110

What did you see instead?

Received  1  from  10.16.83.185:51386  to  0.0.0.0:11110
Received  1  from  127.0.0.1:58306  to  0.0.0.0:11110

So what shoud i do to get the "expect" result? Thanks.
