I understand it, he has a workstation on work without any rights to change a network configuration or make an VPN dialout. Then he can only make changes over the server-manager who is accessible from the Internet.
It is dangerous, yes, but it is his own risk, and when he ask for a method to access the server-manager from the Internet an opened it, thats his problem.
My httpd-admin is open for public access because my OX User must change their password themself. And, do you know on whitch dynamic IP is an SME?
My SME is open for the last six months, and till today, there's no security problems. Only on FTP Port my SME register requests, but not on Port 443.
Changes in configuration db directly, you made with vi or mc.
