Hi,
I am wondering if someone could help me to understand a bit more about the
internal mechanism of proxy_challenge?
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.
What is the reason why this is happening? How does proxy_challenge work
exactly?
Thanks in advance for your help.
Regards,
Mark
