Hi, Is it possible to have multiple binds on a single socket instance? Say I have two multicast addresses that share the same port and use the same nic. On linux I would bind like so: listenEndPoint1(multicastAddress1.to_v4(), port); socket_.bind(listenEndPoint1); socket_.set_option(asio::ip::multicast::join_group(multicastAddress1.to_ v4(), interfaceAddress.to_v4())); } Can I then perform a second bind and join for the other multicast address? listenEndPoint2(multicastAddress2.to_v4(), port); socket_.bind(listenEndPoint2); socket_.set_option(asio::ip::multicast::join_group(multicastAddress2.to_ v4(), interfaceAddress.to_v4())); } If this is not possible or good practice, what would be the alternative?
