For what it's worth, the prefix (.*)/(.*) $1 is not relevant to
the L3 routing of traffic (ie no P2TP tunnel or such) but rather
is relevant to how the login is authenticated.
The prefix tells the network access server (or the authentication
infrastructure) to which authentication servers to send the login
authentication request.
