Dear All, This is my first email to the group so please excuse if I have not followed any rules. Auth and IP Set up: Student devices > Freeradius server > Firewall > ---à eduroam Homeserver Ø Windows DHCP server Ø Unifi WAP portal Network : Student devices connect to Unifi WAP > 2 tagged VLAN Aruba/HP switches > Windows DHCP server has 2 separate subnets Issue: We have set up 2 Vlans to segment the buildings and assign static vlans on the switch ports that connects to the Unifi AP. Depending on the VLAN X or VLAN Y, the DHCP server should provide ipaddress from one of the subnet. Since the windows server upgrade on April 2020, the end devices are picking only X subnet ipaddress. Y subnet is not issued. I have tested with a test vm, can confirm that the Y subnet is issued. I have also used the old windows DHCP server ip address but no changes. Does Free Radius setup has any role in this problem? Regards, Jerome
