Golang中的UDP代理

Question

I am trying to create an UDP Proxy in Go without success.

My objective is to get the DNS response from a server and write it back to the client.

$ kdig -d @0.0.0.0:8853 facebook.com

n, client, err := u.server.ReadFromUDP(buf) // read request

n, err = u.server.WriteToUDP(buf, client)  // write it back

Should i be doing something different? Response:

WARNING: response timeout for 0.0.0.0@8853(UDP)

PS: My TCP Implementation works fine.

Thanks!
