Xdebug: connection from any host

Question

I'm using Xdebug on a virtual machine (Ubuntu guest). I'm using Vagrant to manage these VM and I'm configuring a "pattern" OS to clone it for web develop. The problem is that I want to configure this ubuntu guest to accept connection to xdebug from any host (xdebug is obviously in the guest os).

These instructions don't work:

zend_extension=/usr/lib/php5/20090626+lfs/xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler="dbgp"
xdebug.remote_connect_back=1
xdebug.remote_port=9000

The only way seems to add a line with:

xdebug.remote_host=sdurzu

"sdurzu" is the hostname of the host, but I want to create an "universal" configuration for xdebug, not based on host name or IP.

Is there a way to use a wild card (*) or something like this?

According to the Xdebug settings documentation, remote_host is ignored if you have remote_connect_back enabled.

xdebug.remote_connect_back
Type: boolean, Default value: 0, Introduced in Xdebug >= 2.1

If enabled, the xdebug.remote_host setting is ignored and Xdebug will try to connect to the client that made the HTTP request. It checks the $_SERVER['HTTP_X_FORWARDED_FOR'] and $_SERVER['REMOTE_ADDR'] variables to find out which IP address to use.
[...]

Also, remote_connect_back should allow any device to connect to Xdebug that has access to your web server.
