Dear Mr. Sebastian Weber,
Is it possible to bind admin interface to localhost (127.0.0.1) instead of INADDR_ANY (0.0.0.0) ?
The problem is that Windows Firewall always pops up if an application binds to 0.0.0.0.
Even if it is unblocked, it will pops up again the next time httptunnel_client start, because PAR create a different directory in temporary folder which will be considered a different application by Windows Firewall.
