Vlans and different subnets behind red 20

Question

Hi following setup, simplified to explain 
 an UTM on an sg320 with a red sd-20 
 
 managed switch with vlans on main side 
 
 managed switch behind red with vlans 
 
 red is setup in split mode 
 Main office 10.0.0.0/16 ( vlan 1 ) 
 
 remote side behind red 172.17.19.0/24 ( vlan 1) managed by UTM 
 remote side second vlan 10.106.1.0/24 ( vlan 1001) 
 
 created a red vlan device with vlan 1001 with IP Address 10.106.1.1 
 have a device in this vlan (10.106.1.11) 
 
 from the utm I can access the 10.106.1.11 but I cannot access 10.106.1.11 from Main office 
 i have created static routes entry in UTM but it does not work

Hello Olaf, 
 have a look here: What is the step to configure SD-RED 20 with VLANs? 
 So this is not supported on a RED SD-20. 
 I would recommend do solve this with routing and not with VLAN. 
 So you have to connect two networks over a transfer-network. Identify your gateways, setup static routes and you are done.
