I would apreciate if smb would be able to answer the following question: is there any way of modifying the values of RADIUS
attributes received from the network equipment when passing them to the back-end authentication server?
The purpose for that is letting the back-end server think of SRC-PE cluster as a single entity, so no matter which controller sends the authorization or the accounting requests, NAS-IP-ADDRESS must be the same.
Configuration examples are much appreciated
I think filters in SBR should help.
A filter is a collection of rules for adding, modifying, or removing attributes or attribute values in RADIUS requests and responses.
I think there's another solution here. I may use a single .acc file for both SRCs and specify a value for the appropriate DB column in static manner ('184.108.40.206').
Did you got a chance to test the INSERT statement using static values.
As far as my understanding goes, Values section of accounting files only support RADIUS accounting attribute and pre-defined SBR items.
Yep, I tried using static values instead of %variable or @attribute-name.
Seems like working.
