Hello, can we configure a pair of MX as warm spare (Active/Standby) when in passthrough (bridge/transparent) mode? The following doc does not list it as not supported: https://documentation.meraki.com/MX-Z/Networks_and_Routing/Passthrough_Mode_on_the_MX_Security_Appliance_and_Z1_Teleworker_Gateway   Warm spare doc lists only Concentrator (one-armed) and NAT modes as supported: https://documentation.meraki.com/MX-Z/Other_Topics/Warm_Spare   The following doc seems to say its only supported in VPN concentrator (one armed) or NAT modes https://documentation.meraki.com/MX-Z/Deployment_Guides/VPN_Concentrator_Deployment_Guide   Any input appreciated! Thanks! ... View more
