Lennard, Filtering based on host name is tricky, because the "efficient" way to do it involves a reverse-DNS lookup on the IP address of the incoming connection. With dynamic DNS services, though, this won't actually resolve to the "correct" name, so it won't work.
The other key point to remember is that Hosts-based filtering is primarily used so that unknown hosts can't attack your machine, because the server will drop connections from them without processing them. This protection is less useful if their attempt to connect causes your server to spend resources looking up DNS names, and is completely useless if they manage to compromise your dynamic-DNS address... :) Cheers, Wez @ RealVNC Ltd. > I would like to acces my vnc server, which has a static ip, > from home where i have a dynamic ip.
