Dear FreeRadius Mailing List, I hope this email finds you well. I am reaching out to request assistance with a technical issue that my team and I have been facing while configuring FreeRadius for our OpenVPN setup. We have configured OpenVPN with the OpenVPN Radius Plugin for authentication and accounting, and we have connected it to a FreeRadius server. Our aim is to split users into two groups, Premium and Limited, and configure bandwidth throttling for them depending on their group. For Premium users, we would like to provide unlimited bandwidth without any throttling. However, for Limited users, we want to provide free 1GB/day and then throttle their connection if they exceed the limit. To achieve this, we have configured the PERL module as an External Scripting functionality to check daily consumption and other metrics of the user in "Acct-Interim-Updates." We use this functionality to control the user's group by switching them from Premium to Limited and vice versa. Additionally, we apply throttling to the OpenVPN server using tc. We also allow users to purchase tokens to top up their allowed bandwidth. If a user exceeds their daily limit, their purchased credits allow them to continue their internet usage without any additional throttling. However, we are facing issues with the accounting per user group. Specifically, we have noticed that if a user is now in the Limited group and consuming traffic on a throttled connection, the daily_consumption metric continues to add up, even if they have already exceeded their allowed daily bandwidth. For example, let's say a user has consumed 0.5 GB in addition to their allowed 1 GB per day, which makes their total consumption 1.5 GB/day. If the user then purchases extra credits worth 0.2 GB, their total allowed consumption would be 1.2. GB/Day, however, their actual. total daily consumption would still be 1.5 GB/day, which renders the user in the same `limited` group and breaks the accounting purposes. To address this issue, we would like to have split accounting for each group. In other words, once a user is throttled, we want to ignore the bandwidth recorded and only calculate the bandwidth consumed during their Premium group connection. It is important to note that the `acctinputoctets` and `acctoutputoctets` values are pushed by OpenVPN-Radius Plugin as total incremented values of the connection , and not interval values during each `Acct-Interim-Updates`. We would greatly appreciate any assistance or guidance on how to achieve this goal. Thank you in advance for your time and expertise. Best regards, Ahmad R. Gharib -- ~ ~ *Ahmad R.
