2 Vlan , only one reserved ip possible for one device ??

Question

Hello , 
 
 I have 2 SSID Data (vlan 10) , building (vlan 20). 
 I have one mobile device who sometimes connect with data , sometimes with building. 
 I can make a reserved IP on Mac adres for vlan Data (10) , but i can not reserve another adres for vlan Building (20) 
 Is there any way to solve this ?

Hi helmut, 
 Thank you for reaching out to Sophos Community. 
 Upon testing on my Firewall DHCP, I was able to create both MAC binding(with the same MAC) with both my DHCP pools. 
 2 VLANs are associated with different SSIDs. 
 If you have any errors you&rsquo;re getting, kindly share some prompts you're receiving upon creating the MAC binding.

Hi, 
 there is a setting which will enable reservations on both networks, i can't remember the syntax. 
 Please review this thread to see if it helps?
