<div>hi all-</div>
<div> </div>
<div>i have the following setup:</div>
<div> </div>
<div>1. ser running on 5060</div>
<div>2. nathelper/rtp</div>
<div>3. mysql database w/digest authentication</div>
<div> </div>
<div>now, i have a client on a private network (NAT) behind a firewall. port 5060 tcp is on the firewall is open as well as 35000 to 37000 UDP (rtpproxy is set to run between these ports).</div>
<div>when i plug the client into a regular, non-firewalled home router, it registers properly (register->401->register again->OK)</div>
<div>when i put the same client behind the firewall, it 401's twice.</div>
<div> </div>
<div>i am 100% sure the password is correct. </div>
<div> </div>
<div>is there something else that needs to be open? I dont really understand the authentication mechanism - does the password come via a different port or something like that?<br clear="all"><br> </div>
