So my question is: Does FreeRadius have built in support for taking responsibility of Accounting retransmission?
No. It's up to the NAS to retransmit.
I currently proxy to an upstream vendor on the off-chance my customers use their services while connected to a servicing NAS.
What does that mean?
Accounting turn-around with them is not robust so a NAS gener! ates a truck load of duplicates then wonders why the accounting server hasn't responded. Optimally, my own Server would reply and then generate a new accounting record for my upstream vendor. Also, with the current setup, if the upstream vendor goes offline, my NAS will continue duplicating accounting records until timeout.
I don't control all the connecting NASes so I can't tell them to wait longer. Overall, it seems simpler to cut the upstream vendor out of the middle of my accounting stream.
