Have apache 2.x running virtual hosts on suse 9.0 hosted by an ISP, but

have access to box.
need to send http requests down a VPN to a W2003 box in different
This box is already accessed as a file server by a few people via a VPN

with windoze clients.

Can someone advise what options there are? A VPN client is obviously
needed for the suse box, plus probably some addition security to only
allow http requests from the suse box onto the W2003 box. Plus some
additional work on the apache 2 webserver perhaps? A proxy maybe to
ensure security in the other direction.
Not sure if the connection needs to be permanently up. requests are not

likely to be that frequent or intensive (,important tho ;-).
