Ricardo_J, you can apply group policy to a subnet but instead must use the VLAN method. In doing so you would need to move the VLAN routing to the MX for that method to work. The thread below discusses a similar scenario and the second link is to the Group Policy documentation. https://community.meraki.com/t5/Security-SD-WAN/group-policy-per-vlan-and-switch-setting/m-p/24114 https://documentation.meraki.com/MR/Group_Policies_and_Blacklisting/Creating_and_Applying_Group_Policies#Applying_Group_Policies I hope that helps.
