I have the following setup:

internet (ADSL)
.
router
.
firewall
.
switch
.
PCs

I have a block of real IP addresses and the firewall is running in
stealth mode (invisible to the network from both sides). Some incoming
ports on one of the PC's are accessible (SMTP, HTTP, NNTP servers) and
the rest are blocked.

I have a laptop, which I would like to allow to connect to the network
from a dial up ISP (via a dynamic IP allocation) when I am out and
about. I would like to set up a VPN. The firewall, unfortunately, does
not act as a VPN server, but will pass traffic through as will the
router.

I will have to run a VPN server on one of the PCs. From what I can
understand from the Win2k server help file, that machine will need 2
network cards.

How should I attach the two network cards to my network? Just give them
sequential IP addresses and attach them both directly to the switch?

How do I tell the machine to only use one of the network cards for VPN
traffic and the other for everything else but VPN traffic?

Why can't I just do it with one network card?
