hello,

ppp term of remote means the box you dial to.
for example :

boxA dial to boxB then in the boxA to dial remote name must specify the username of boxB. and - in the boxB itself must specify its name as boxB.
this way so both the caller and receiver can auth them selves.

boxA:
username boxB password boxB

boxB:
username boxB password boxB

cheers.
