|
# tunnel request", and "outer.reply" means "outer tunnel
|
|
# reply attributes".

|
#
|
|
# This example is most useful when the outer session contains
|
|
# a User-Name of "anonymous@....", or a MAC address. If it
|
|
# is enabled, the NAS SHOULD use the inner tunnel User-Name
|
|
# in subsequent accounting packets. This makes it easier to

# track user sessions, as they will all be based on the real

|
# name, and not on "anonymous".

|
# real user name to any intermediate proxies. People use

# "anonymous" identifiers outside of the tunnel for a very
|
|
# good reason: it gives them more privacy. Setting the reply
|
|
# to contain the real user name removes ALL privacy from
|
|
# their session.
|
|
#
|
|
# If you want privacy to remain, see the
|
|
# Chargeable-User-Identity attribute from RFC 4372. In order

|
# to use that attribute, you will have to allocate a
