(n00b here) Someone mentioned above, and so I ask: have you given banana-pi r1 with openwrt a try? Would that setup be simpler than the current one with VLAN and netplan? Speaking of netplan: I didn't quite catch head or tail of it. What does it do and why is it required (in the context of the setup). For ex: ethernets: enp2s0f0: dhcp4: no # only dhcp6 allowed? # or, is dhcp now handled by wifi-ap? enp2s0f0.10: id: 10 link: enp2s0f0 # down-link? addresses: - 68.69.70.71/24 # is this modem's public-ip subnet? # or, could be anything? gateway4: 68.69.70.1 # modem's public-ip? enp2s0f0.20: id: 20 link: enp2s0f0 # up-link? addresses: - 192.168.0.1/24 # subnet for the internal network? # what does dhcp for this one? > So all the routing and NAT that needs to happen, just happens on those two virtual interfaces instead. The managed-switch NATs traffic? Or, you mean to say that rpi4 does? Or, am I misunderstanding how all of this actually works? Thanks.
