Hi Alan,
It will check Simultaneous-Use in the inner-tunnel, but it may not have access to all of the session data.
And you've got to ensure that the User-Name in the Accounting-Request packet is the same as for the Access-Request. i.e. not "anonymous".
That's exactly the problem. I decided to upgrade to the 3.0.8 version freeradius. Now I can clearly see the values of usernames. ################ Access-Request (88) Received Access-Request Id 35 from [NAS_IP]:23710 to [FR_IP]:1812 length 181 *(88) User-Name = 'myuser@mydomain'* (88) NAS-IP-Address = 172.19.13.15 (88) NAS-Identifier = '24a43cb0fbad' (88) NAS-Port = 0 (88) Called-Station-Id = '2A-A4-3C-B2-FB-AD:mySSID' (88) Calling-Station-Id = '34-BB-26-C2-1D-60' ################ Proxying Access-Request (88) Proxying request to home server [proxy_IP] port 1812 timeout 20.000000 (88) Sent Access-Request Id 92 from 0.0.0.0:46389 to [proxy_IP]:1812 length 191 *(88) User-Name = 'myuser@mydomain'* (88) NAS-IP-Address = 172.19.13.15 (88) NAS-Identifier = '24a43cb0fbad' (88) NAS-Port = 0 (88) Called-Station-Id = '2A-A4-3C-B2-FB-AD:mySSID' (88) Calling-Station-Id = '34-BB-26-C2-1D-60' ################ Access-Accept from proxy (100) Received Access-Accept Id 231 from [proxy_IP]:1812 to [FR_IP]:46389 length 173 *(100) User-Name = 'myuser'* ################ Accounting-Request (101) Received Accounting-Request Id 48 from [NAS_IP]:41124 to [FR_IP]:1813 length 160 (101) Acct-Session-Id = '00001A59-00000037' (101) Acct-Status-Type = Start (101) Acct-Authentic = RADIUS *(101) User-Name = 'myuser'* (101) NAS-IP-Address = 172.19.13.15 (101) NAS-Identifier = '24a43cb0fbad' (101) NAS-Port = 0 (101) Called-Station-Id = '2A-A4-3C-B2-FB-AD:mySSID' How to ensure the same username in the Accounting-Request and Access-Request? How to configure proxy response in format user@domain? Best Regards, Renato
