Thank you Alan for your quick response. So then I have one question about Acct-Output-Octets. If I have got this values, this means NAS is not sending the correct values, right? MariaDB [radius]> select acctinputoctets,acctoutputoctets,username from radacct; +-----------------+------------------+----------+ | acctinputoctets | acctoutputoctets | username | +-----------------+------------------+----------+ | 35441 | 0 | rdiaz | | 10935 | 0 | rdiaz | | 30346 | 0 | rdiaz | | 1694 | 0 | rdiaz | | 109733 | 0 | rdiaz | | 402521 | 0 | rdiaz | | 362871 | 0 | rdiaz | | 4010 | 0 | rdiaz | | 0 | 0 | rdiaz | | 714058 | 0 | rdiaz | | 203308 | 0 | rdiaz | | 12440479 | 0 | rdiaz | How can I debug why NAS is not sending the correct values?
