Wireless and External Windows DHCP server

Question

We are looking to replace Ruckus wireless network with Sophos AP6 420e. 
 Working the configuration of the Sophos WLANs config and I am stuck. 
 I can get test client to connect to WLAN that use vLAN1 but unable to get other WLAN that are tagged (other than vlan1) to connect. 
 We will have several WLAN that use multiple vLANs other than vLAN1. 
 We also use a Windows base DHCP server to handle the IP addresses on the different IP segments for each VLAN 
 I somewhat remember with the Ruckus system that we needed to configure DHCP scope option 43 Vendor Specific Details to get the Win DHCP server to respond to the client with the correct IP address. 
 Does anybody know what the Sophos Vendor Specific Info is or do you think is it something else causing the client not to connect. 
 I am having a tough time trying to locate how to troubleshoot client connections as I am a newbie to it. 
 Any help would be appreciated.

Hello Slappy , 
 Thank you for reaching to Sophos community! 
 Are you looking to deploy as described in below KBA? 
 https://docs.sophos.com/nsg/wifi/help/en-us/UserManual/NetworkSettings/VLAN/index.html 
 Another option is using Guest Network using VLAN. However, currently the AP6 only suppoting bridge mode.

 The NAT mode option is avaialble with the Sophos APX and it will soon be added to AP6 too. The below steps may help! 
 a. Configured Firewall/Router interface with the with the network through which you wishes to lease the IP. b. Create DHCP scope which can assign the IP to AP6 c. Assign the VLAN ID to the Sophos AP configuration. d. The interface which is connected to the firewall from the switch is set as the trunk. e. The AP6 connected from the switch is kept as an access port.
