Use network range in hungroups file

Hi! I would like to compare the Client-IP-Address to a network in the huntgroup file. Since FreeRADIUS 2 I am using something like this:     huntgroup1       Client-IP-Address =~ 192\.168\..* With FR3 I hoped I could use something like:     huntgroup1       Client-IP-Address < 192.168/16 But this results in an Error: Error: /etc/raddb/mods-config/preprocess/huntgroups[56]: Parse error (check) for entry huntgroup1: Invalid IPv4 mask length "/16".  Only "/32" permitted for non-prefix types Is it somehow possible with FR3 to compare the Client-IP-Address to a network range in the huntgroups file? Sincerely, Daniel
