Hi,

I can use boost to query and to resolve TCP connection from a remote server
which has a public IP address:

boost::asio::ip::tcp::resolver::query query(host, port);
resolver.async_resolve(query, boost::bind(&ConnectionClient::handleResolve,
this,            boost::asio::placeholders::error,
boost::asio::placeholders::iterator));

But how can I connect to the remote server which does not have a public IP
address, I have to connect it via route from a proxy server public IP
address?

Thank you.

Kind regards.
