Hello,
Yes, you’ll need a router to manage traffic between LAN networks. A managed switch usually doesn’t handle traffic routing between VLANs. A managed switch works at Layer 2 of the OSI model, allowing it to create and control Virtual LANs (VLANs) for network segmentation. However, it lacks the ability to route traffic between different VLANs because routing functions happen at Layer 3.
