Hi @Yash_03, Sounds like Asymetric path selection is happening here. I'm assuming you have a Switch connected to the MX firewall to service all these VLANs and Hosts. If so, I would recommend confirming the ports on the MX and any downstream switch have the VLAN configuration matching .i.e. Same Trunk details (Native VLANs & Tagged VLANS) or Access VLANs etc. The MX LAN ports do not behave like regular Switch ports. See below guide for further details. https://documentation.meraki.com/MX/Networks_and_Routing/MX_Layer_2_Functionality
