Shorewall users - Apr 2005 - VPN & ping error

Hi everyone..
i have followed this instructions 
http://devel.elucid8design.com/el8/devel/tutorials/pptp.php to build a  
vpn server with shorewall.
the configuration of my network is:
vpn server (with shorewall installed) with 2 interfaces: 192.168.1.2 --> 
net zone
                                        
                                         192.168.0.x --> loc zone
when i try to connect two clients with addresses 192.168.1.x, the pptp 
server give me the address 192.168.0.4 for one client and 192.168.0.5 
for the another client.
Everything seems ok and if i try  ping from a pc in the loc or fw zone 
to the vpn client i have a response and vice-versa, but i can''t ping
the
vpn clients each other. The result is host unreachable.
Where is my error?
thanks in advance to all
W.

Try adding the ''routeback'' option on the pptp entry in
/etc/shorewall/interfaces. If that doesn''t work then please submit a
problem report as requested at http://shorewall.net/support.htm#Guidelines
