Something like 192.168.x.y? If so, you can't connect, that's true, if there's not a nat gateway substituting the private address by its public address in every ip packet. If you can access web pages from your private ip system, that's probably because of a proxy server in your network which fetches pages from the outside if required from within the local network.
