Hi, i am trying to setup external radius server with mikrotik ccr2036. I am using freeradius. Its configured basic with linelog. I want to use dhcp authentication on my mikrotik via radius. Linelog working but if new device cant authorize via radius dhcp. Configuration of freeradius is correctly. But i dont know why its doesn`t working. (If any device connection i am getting error in log - RADIUS server is not respondig, but I can ping my virtual machine by mikrotik)
It’s be a while since I last setup RADIUS but, from memory (and on Windows Server - sorry), you need to authorize each client device on the RADIUS server. Have you done that for the new device yet?
The other thing to do is check that the appropriate RADIUS ports are open (had that problem on MS Server 2012R2). You can check by scanning UDP ports 1812 and 1813 using nmap
nmap nmap -p 1812,1813 -sU 123.456.789.012
where 123.456.789.012 is the IP of the RADIUS server (ping only tells you that the computer is alive not that RADIUS is working).
