I'm going to guess that you mean the Internet can't see your WHS, not that your WHS can't see the Internet (if you Remote Desktop into the WHS, can you access web pages?). If so, you need to look up Port Forwarding for your router(s) if WHS can't use uPnP to set it up automatically. If your router works with uPnP, I believe WHS will set up ports 80, 443, and 4125 to forward.
