vb.net VPN client

Hey All me again,

Right can anyone point me in the direction to be able to make a vpn client contained within my application....?

I have a central DB sat on a server behind a pix 501 firewall and vpn host, my software simply connects to the server holding the database, all works fine if you sat in the office and on the internal network, so i figure ok we have a pix why not use this to make a vpn connection that way, when a remote client connects because of getting internal network settings we can see the db and everything works fine, (tested with cisco vpn client v6) so ok my remote worker currently have to open the cisco client connect then open my program and off they go.....

all i wana do is build a vpn client of my own into my app

some one point me in the right direction please
