[pptp-server] ppp remote user

[Dung Nguyen]

Dear
Thank you for your helping me.I understand you, but I
want to mean that :
 -----		-------			 ------	
|  A |----------|  B  |------------------| C  |			
 -----	PPP	-------		pptp	 ------ 


And these are things I've done :
_ I establish a ppp connection from A to B
_ After that I make a pptp connection manually from B
(pptp linux-Client) to C (PoPToP linux Server)

_ After that I can't ping from C to A
_ If i do manually : route add -net <address A> gw
<Address B> at C(PoPToP Server) : I can ping to Remote
host A
_ My question is how to ping from C to A automatically
because We don't know the dynamic address of the
remote host A (Is assgined by B), so I can't add to
ip-up.local scripts.
If you have time , Please help me.
Thank you very much.
