Hi everyone,

is there a reason why WITH_UDPFROMTO is not enabled by default on Linux
and FreeBSD systems?
Shouldn't the autoconf notice that this feature is supported on the host
system, and accordingly activate the feature?
I believe that the feature is only available on Linux and FreeBSD, but I
might be wrong.

It took me a while to go through the code and find that feature. My
Linux based server would not respond with the right address when
configured to bind to *. (this is v1.1.4 I am talking about)
At first I suspected a bug and wanted to fix it. Then I realized that
everything was already there, but not activated.

./configure --with-udpfromto

activates the feature. The server now responds with the right IP and
everything works flawlessly.

The switch --with-udpfromto is explained nowhere in the INSTALLATION
file nor in the webbased documentation.

A couple minutes ago I added the hint to the freeradius wiki. So
hopefully others will find this feature more easily.
