I currently have a Microsoft Exchange Server 5.5 that uses its own dial up
modem to connect to our ISP every 2 hours and download mail. I desperately
want to remove the modem from the Server and get Exchange 5.5 to connect to
the ISP through a FreeBSD box configured to do demand dialing and NAT via
I have everything configured correctly and working but I don't want FreeBSD
to bring the line up everytime something needs emailed out of the office. I
only want it to dial up every 2 hours or so but I do want it to dial
immediately if someone wishes to browse the Web or FTP, etc.
Has anybody out there performed something similiar? The schedule part of
Exchange only works if you have a modem directly attached so I can't think
of any other way at this end to set up the 2 hourly interval. Maybe there
is something that can be done at the ppp end?
