missing gw in pptp

[nivw]

hay
couldnt find it on google for a week now..

I seek help in vpn from win2000 to linux (gentoo) running pptpd
when I vpn from linux to that server, the gw is the server address - which is fine
when I vpn from win2000 to the server , the gw is the client address.

how to fix?
where to post?

thanks
