Hi, Juli,<div><br></div><div>I've created the server and client conf files, and both the server side and the client side wanproxy seem to be running. You mentioned that I can send some random files over http to the client and wanproxy will forward it to the "intranet:80". I am not sure how should I do this, plus, should there be some process (eg: apache webserver) running on the intranet and listening on port 80 before I can send some random file to it? Could you please be more specific about how I may test to see if wanproxy is working correctly? </div>
<div><br></div><div>Thank you. <br><br><div class="gmail_quote">On Tue, Feb 19, 2013 at 11:53 AM, Juli Mallett <span dir="ltr"><<a href="mailto:juli@clockworksquid.com" target="_blank">juli@clockworksquid.com</a>></span> wrote:<br>

That looks exactly right to me. Is it working for you in practice?<br>
<br>
Thanks,<br>
