Hi Petr, the first issue is probably a misunderstanding what the prefixes in the FileIPAuth rules mean and I have clarified that in the CVS manual a minute ago: The prefixes specify the destination numbers an endpoint with that IP may call and are only checked in Setup messages. The prefixes _do_not_ restrict the aliases the endpoint can register with. Your 2nd issue is caused by the fact that GnuGk can only see the IP of the immediate next endpoint/neighbor sending the call. There is no way to check if that call really originates at that endpoint. If you neighbor may call that destination, then anybody who may route calls through your neighbor may also call that destination.
