	I created the routes and activated IPV4 forwarding on both servers as
per the documentation.  At this moment I think that the main router at
each site is not properly configured to route the VPN networks and that
is why I get no answer from remote machines.  Unfortunately I do not
control the other router so I have to wait until they can confirm
routing is properly implemented.

	Thank you for your response.
