I noticed something crazy that I hadn't noticed before

on i use this command

show ip int brife

interface Virtual-Template8  is down 

down status and down protocole

that normal Virtual-template always Down, 

config LO and assign IP 
then ping this LO

one more point 
print route
ipconfig 
in client PC and check if the client get IP from VPDN router
