Unable to ping remote site

[Guest]

I have built a Windows 2003 server with a local NIC and an ISDN TA. The TA
can connect to various remote sites that we support. For example I have site
A and I have given this a static route (in RRAS) of 192.9.200.0. When i ping
this IP address from the RRAS box it connects across ISDN & I get a response.
If I repeat this ping from a client machine i just get a "request timed out".
However the RRAS box has seen the request as it brings up the ISDN link. So
something small is missing from the chain.... Thanks in advanced.

A RAS connection is designed as a client-server application. When you
connect, the server sets up only a host route back to the client.

A machine on the LAN behind this machine will not be able to use the
connection because there is no return route. To link sites, you need to use
a LAN to LAN connection (also called site to site or router to router
connections). These connections use demand-dial interfaces on the routers at
both end of the connection, and you can link subnet routes to these
interfaces.

Thanks for your reply Bill. So I would have to create a VPN link between
sites? The biox would have to dail the ondemand link then create the tunnel?
That along the right lines?

That is basically it. The "answering" router needs a subnet route back
to your private LAN through the RAS link if you want machines behind your
RRAS server to see the remote site. Adding a route at your end isn't
sufficient. The traffic must have a return route as well, and that can only
be configured on the "answering" router.
