 I agree ...

 How it is difficult? It will easily be done through IPCP negotiation.
 In my opinion, during IPCP negotiation if the dial-in client does not have
 any IP address, let our proxy-client request DHCP server to give an IP address 
 and hand it over to the dial-in client. What is the special processing 
 required on dial-in client side? 
 	The only question that remains is whether the dial-in client's IPCP 
 negotiation will wait until the proxy-client obtains the IP address from the 
 DHCP server ( which can be even of the order of minutes).
