NT Workstation Peer Web Services Questio

I have installed Peer Web Services on NT Workstation at home. What I’d like to know is – is there any way to use my modem with Peer Web Services so I can dial in from work and use it as a private Web page/ftp server?

In addition, is there any wayto “dial up” my home computer through my LAN? I know that is a strange question, but I’m wondering if there is some kind of way this can be done instead of using a separate modem (we have no analog phone lines in our offices).

Thanks in advance for your help.
