IIS & Remote Access VPN Server

Can you have IIS and a remote access VPN server running on the same machine,
or does the remote access server need to be dedicated soley to VPN
functionality?

I currently have a Linksys firewall/router connecting a Win2003 & WinXP Pro
machine. I was trying to run the remote access server on the Win2003
machine, which is the same machine that's housing SQL Server-IIS web
service... but it seems that the remote access server hogs the network card.
Also, note that the LAN is connected to the internet through a dynamic IP
address (i.e. dyndns.org).

Can I set up my XP machine to run as a remote access server for my LAN? I
have two network cards on that machine, but only one RJ-45 port on that
machine.

What are my options?

thanks,
Ivan
