In professional networking installations, particularly within hospitality settings like hotels and MDUs, we structure networks much like the design shown. Rather than chaining devices through firewalls, gateways, and switches, each component connects to a central “Core Switch.” Traffic directions are managed using VLANs. We assign one VLAN for all internet-connected devices with public IPs, another for firewall internal subnets, a third for switch management, and additional ones for AP or management tasks. This approach enables remote adjustments and quick failover—such as if the gateway handling user authentication stops working—so we can instantly reroute traffic through the firewall’s VLANs. This method eliminates the need for consumer-grade routers, which typically lack robust VLAN capabilities regardless of firmware. Using a switch as the Core Switch and an Archer as a simple AP (plus extra LAN ports) provides clear separation of responsibilities, making troubleshooting more straightforward.
