Hi Team, I would like to ask your help about IP address comparisons in FreeRADIUS 3.0.27. I want to restrict a mac-address to a network, but comparison of ip address with a subnet doesn't seems to work as a check items : 11-22-33-44-55-66 NAS-IP-Address < 192.168.8.0/22 /etc/freeradius/3.0/authorized_macs[10]: Parse error (check) for entry 11-22-33-44-55-66: Invalid IPv4 mask length "/22". Only "/32" permitted for non-prefix types Yet, documentation says it should be possible. "The syntax allows conditions such as 192.0.2.1 < 192.0.2/24. This condition will return true, as the IP address 192.0.2.1' is within the network `192.0.2/24." I also tried casting the attribute, without success : 11-22-33-44-55-66 <ipaddr>NAS-IP-Address < "192.168.8.0/22" /etc/freeradius/3.0/authorized_macs[10]: Parse error (check) for entry 11-22-33-44-55-66: Invalid attribute name Do user files have a different behaviour for comparisons and casting ? I could use regex as a backup solution but it's quickly going to get difficult to read in the file : 11-22-33-44-55-66 NAS-IP-Address =~ "/^192\.168\.(8|9|10|11)\./" https://freeradius.org/documentation/freeradius-server/4.0.0/raddb/mods-conf... https://freeradius.org/documentation/freeradius-server/3.0.27/unlang/conditi... https://freeradius.org/documentation/freeradius-server/3.0.27/unlang/conditi...
