Vlan Assignement depending on Ip source adress

Hello, I have configured a freeradius V3 with automatic VLAN assignement, all work fine. I want to know how it is possible to assign a VLAN depending on the IP source Adress. For Exemple : If user A connect freeradius from 18.18.18.18 (public ip) ==> Assign VLAN 1 If user A connect freeradius from 22.22.22.22 (public ip) ==> Assign VLAN 3 If user A connect freeradius from 34.34.32.12 (public ip) ==> Assign VLAN 22 Thanks for your help.
