Hi, I want to implement an UDP server and have problems on defining on how the server handles coming concurrent udp "connections" from multiple clients. What I basically want to implement is an DNS proxy. Is there something equivalent to an tcp::acceptor for udp ? Looking over asio docs I see: template< typename Protocol <http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/Protocol.html>, typename SocketAcceptorService <http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/reference/SocketAcceptorService.html> = socket_acceptor_service<Protocol>>class basic_socket_acceptor : public basic_io_object< SocketAcceptorService >, public socket_base For tcp we have following typedef: typedef basic_socket_acceptor< tcp > acceptor; Can I use basic_socket_acceptor with socket_acceptor_service<UDP> so that I can create additional udp sockets for every udp client that wants to send data to my server ? I've observed that if I use async_receive_from on the same socket I receive data from multiple clients making impossible exchanging data (read/write) with multiple clients at the same time. Any hints are appreciated. -Ghita
