How does it depend on the PPP client at the dial-in client end? Can't the whole
process be handled by the proxy DHCP client as a part of IPCP negotiation?
But the questions arise whether the dial-in client will wait for say 2 minutes
(in the worst case) for IPCP negotiation? Also what action should be taken when 
lease for the dial-in client expires (since it could not be renewed for any 
reason)? It is not proper to break the connection abruptly. Then what should be
done? 
     Any thoughts on these issues will be highly appreciated.
