I thought cups would only do this with 'HostNameLookups Double' but not with 'HostNameLookups On'. Or did I miss something?

Sorry, I think I wasnt clear enough. What I want ist to do some administration jobs on a system that is located somewhere else. The remote system has amodem connection and my has a dsl connevtion, both with dynamic IPs from different providers. I would like to configure cups in such a way, that I am able to access the web-frontend of cups only with my system. So it wont help me to allow access from a local subnet.

The only reason why I tried this only on my system was because the remote system had no connection at that time.
