Thank you for reply. I found the problem. I missed a field during nas table analysis. The field was "server, varchar(64). I added it. I had also to - clear clients.conf from NAS manually added to avoid duplicates; - set one NAS address, formerly added, as Host address instead of subnet. Now it works fine! Now backup of configuration and going to work on chiphering passwords and manage WiFi. Superataru. reply to . . "Your message doesn't have enough information to troubleshoot your problem.
