Question : Problem: Best VPN software - to access Microsot Access database through Web Browsers

Hi there
I have server 2003 ent edition domain with Xp professional client machines.  At the moment my clients use (microsoft server 2003 built in vpn connection, with RRAS) VPN to connect to my Access database from home.  The configuration is like this, they dial in first then use remote desktop to work on access database.  Everything works nice.  Sometimes the clients get the error messages because of different types of firewalls they have at home (may be in there routers etc) and cause trouble for them to even connect.
My question is:
WHich is the best (or one of good ones) VPN software available right now by which I can access my 'Access database' from a web browser?  It will be nice to find one with which I do not have to extend the ports in my main router which is Cisco 2811.  Any other suggestions are welcome.
Thanks
