Hi All, I have a setup as shown in the below figure (CUIissue.jpg) At step 3. the proxy AAA add the CUI to the radius access packet.and step 4 forward it unmodified to the NAS. NAS is supposed to send the CUI with the radius accounting requests, however the NAS is not supporting that and dropping the cui value. I read about the cui support in freeradius however it seems to be used in generating a new one and adding to the packet. In this case I need to add the CUI receiving from the proxy AAA to the accounting packets coming from the NAS. I could record the received CUI at step 3 and add that value to the accounting packet at pre-proxy stage 5>6, however the challenge is to find a correlation between the packets. Has anyone came across such a use-case and were there any solutions available? Appreciate your comments.
