Connect wired LAN segment via WiFi

Assume a typical WiFi home network. In one room of the house, there are several devices that want to be connected to the network, but not all of them have WiFi (e.g. Ethernet printer). They cannot be wired directly to the router.

I'd like an Arch Linux box in that room to connect to WiFi, and allow the other devices in the room to also access the network by connecting them to the Arch box's Ethernet port via a switch, and have the Arch box forward traffic via WiFi. How would I set this up?

I guess I could turn the room mini-network into a separate subnet and use the Arch box as a router. That would require some routing configuration on the main router, I presume, so the rest of the network can find machines on the room subnet. (Is that right? If so, I'd like to avoid that.)

Or I could connect the Arch box's Ethernet and WiFi via a virtual bridge. In which case, all devices (WiFi, and the ones on the room network) should be peers on the same subnet. Does this sound like it might work?

Yes, it would seem so.

Might be late to reply but bridging wireless doesn't work well unless both sides supports WDS or 4-addr format in the packages.

If they don't support it then routing or proxy-arp might be the best solution if wired ethernet cannot be provided to the secondary site.
