Well, it depends what kind of vpn you mean...

If it's ipsec, you'lll need to open udp:500, esp(protocol 50), and
possibly ah?(protocol 51). if you're doing NAT traversal, you may need
to open udp 4500 i think, (not too sure, don't use it myself)

If it's pptp vpn then you need to open port tcp:1723 and protocol gre.

Hope this helps some,
