[asio-users] Boost asio - udp server

[Gheorghe M. <ghe...@gm...>]

I saw the official async udp server example from boost doc. There you
create a single udp socket, bind it to a local port and do something like
this:

socket(ioService,
boost::asio::ip::udp::endpoint(boost::asio::ip::udp::v4(), port))

socket.async_receive_from(buffer(data, max_length), senderEndpoint,
boost::bind(&Request::HandleReceiveFrom, this,
    boost::asio::placeholders::error,
      boost::asio::placeholders::bytes_transferred));

How can I handle multiple concurrent udp connections from clients, because
if I try to create another socket using

socket(ioService,
boost::asio::ip::udp::endpoint(boost::asio::ip::udp::v4(), port))

i get bind errors because I already have a socket bound to the same port

Some more about the udp server I want to implement. I use my server as a
dns proxy. I want to handle multiple clients, proxy their requests, and
give answers back.
If I could use something like tcp acceptor, but for udp that would simplify
things as I see them now.
