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.
