Hi,<br><br>I am wondering if someone could help me to understand a bit more about the internal mechanism of proxy_challenge?<br><br>If the UA is connecting to the server using the external ip, proxy_challenge fails, but if the UA is connecting to the server using the lan ip, proxy_challenge succeeds. <br>
<br>What is the reason why this is happening? How does proxy_challenge work exactly?<br><br>Thanks in advance for your help.<br><br>Regards,<br>Mark<br>
