VPN has to be on an internet accessible IP.  You can set up an ACL or
static/conduit to give the internal VPN box a public IP.  Make sure you open
the correct ports.  tcp port 1723 and gre need to be opened to it.  As long
as you're not using PAT it will work.  Hopefully you have a free public IP
you can assign to the box or it won't work unless you use the PIX as the
IPSec VPN with Radius or TACACS+.
