Diablo - 2006-10-29

I've installed Webmin 1.230-1 on Ubuntu 5.10 Linux.
After installing I configured in miniserv.conf allow=192.168.15.150 (my IP,not the server IP).
The first problem is that after running server lives very small time, may be less a minute.
The second problem is that I can't connect from another computer with IP 192.168.15.150 to Webmin. It showes me a page with next text: Error - Access denied for 192.168.15.150.

Please, could you help me solving these problems. If additional info is needed - write.
