Checkrad and IPv6 NAS IP address

5 Sep 2021

      Hi! I would like a help if possible, please.

I have a NAS Mikrotik configured with IPv6 only.

All packets arriving for FreeRadius have only the NAS-IPv6-Address attribute. NAS-IP-Address attribute is not sent by Mikrotik in this scenario.

I am able to authenticate clients successfully, as well as using the radclient command to disconnect. I'm using MySQL database and changed the query to store the NAS-IPv6-Address attribute in the nasipaddress field of the radacct table.

The problem is with checkrad: when I need to check for simultaneous connections I get the following error:

(0) sql: Executing select query: SELECT radacctid, acctsessionid, username, nasipaddress, nasportid, framedipaddress, callingstationid, framedprotocol FROM radacct WHERE username = 'joseph.test' AND acctstoptime IS NULL
checkrad: Unknown NAS 255.255.255.255, not checking

The IP address that is in the nasipaddress field is 2804:444:1:1::2 and not 255.255.255.255.

Looking for the error message I found the session.c file in the Freeradius project on Github (https://github.com/redBorder/freeradius/blob/master/src/main/session.c). It seemed to me that checkrad is always waiting for IPv4. In any case I could be wrong because I don't know the C language.

My checkrad script isn't even called.

Below is the Access-Request package and the freeradius -X command output.

Would anyone know how to get around this problem? Check simultaneous users using MySQL and IPv6 as NAS IP address?

Thank you very much
Fabricio
