Hi,

We use a lot of PPP Authentication.  

First the user needs to authenticate using a ppp chap authentication.  The ppp chap 
stuff is also checked when the data is being sent to the user on the particular ip 
addess.

so what do we have

router#username freddy123 password 7 xxdds@fdgsrg

This can be up to 700+ users

then

router#int d 0
other stuff
router#dialer map ip (an ip address) name freddy123

And more.

This authenticates the user and confirms that data is going to the expected user.  PPP 
chap authentication does this.
