Create multiple UDP servers using golang

I have a list of ports that I need to create a UDP server. I have tried this aproach

for _, r := range routingTable.Routes {
		if r.Metric == 0 {
			wg.Add(1)
			go func() {
				conn, err := net.ListenUDP("udp4", &r.OriginPort)
				if err != nil {
					log.Fatalf("Error occured starting the server: %s", err)
				} else {
					log.Printf("Listening on port: %s", r.OriginPort.String())
				}
				defer conn.Close()
				buffer := make([]byte, 1024)
				for {
					conn.ReadFromUDP(buffer)
				}
			}()
			wg.Wait()
		}
	}

but it is not working. What can I do to make it work ?

1. as noted by @CeriseLimon : don't make the goroutine block on each iteration, move wg.Wait() outside of the loop
2. don't forget to call wg.Done() from within each goroutine : add a call to defer wg.Done() in each function

(since your listening goroutines never return, the second point is a bit theoretical ... obviously, add some code to have your listening goroutines do something, and exit cleanly if possible)
