pptp vpn problem: can connect but no traffic

Hi,

I've setup a VPN server running pptpd (Debian Woody) following the
instructions from http://www.gfxcafe.com/VPN%20Howto.html.

I can make the connection from any Windows client without any problems
but I can't ping any hosts on the VPN (not even the VPN server host
itself which is 192.168.0.10) and the VPN server host can't ping my
client (an ip in the 192.168.0.51-59 range) either.

The VPN server is connected to the Internet via an ADSL router/modem
(netcomm nb1300 which supports VPN pass through (PPTP/L2TP),IPSec),
I have set up port forwarding for port 1723 in the router.

I have some simple iptables rules setup on the VPN server. I suspect its
either a routing problem or an iptables problem. I have tried several
iptable rules with no luck. I'm not really an expert in networking.

another piece of info, I can connect from 192.168.0.2 (please see below)
which is a Windows box and is on the same subnet as the VPN server, but
the same things happens.

thanks in advance

Song
