#firewall

While the switches do HW offloaded L2 shuffling of packets the core of the network is the firewall. It does the heavy lifting of routing and filtering packets between VLANs & internet. Why I segment the network with VLANs and the choices behind it.

I have used OpenWrt for many years to prolong service life of WiFi devices and get functionality stock does not give. But when the networking became more complex the limitations of the current setup became apparent.
