Re: Issue 130: Diameter Compatibility

This is a problem.

My suggestion is to define the restrict the NAS-Filter-Rule
attribute to the RFC 3588 syntax, and define additional
attributes for other purposes, such as Layer 2 filtering
and HTTP redirect. It is ok if the same general syntax
is used for these other filters, but they need to be defined as separate attributes to enable translation of
NAS-Filter-Rule AVP from RADIUS to Diameter and back.


Sounds like a good suggestion to me.
