OSX Server VPN NAT Help

Hello

Configured ML VPN server using the following article.

http://macminicolo.net/mountainlionvpn

Everything works fine and vpn client can go out to inet. So far so good. Now what I want to do is use StrongVPN on server and allow my vpn clients to go out my connection to strong VPN. So far everything I have tried doesn't work. :-(

Want it to look like this

MYLOCALVPNCLIENT->OSXMLVPNSERVER->SERVEROPEN VPN CLIENT to STRONGVPN

Playing with cusomNATRules:

nat on en0 from 192.168.3.0/24 to any -> (en0)

pass from {lo0, 192.168.3.0/24} to any keep state

tried chaning it from en0 to ppp0 and no go. Did different combinations and still nada. The connection on the server to STRONGVPN cfg to route all traffic through STRONGVPN.

I'd appreciate any help you can give. I'm sure I'm missing something simple.

Thanks!
