Bridging eth0, eth1, and wlan0 to Access Point with DCHP?

[wess.gates]

Hello,

I have a robot network topology as drawn here:

I have attempted bridging wlan0 and eth1 using netplan. I have described or posted the similar questions here:
superuser.com
and here:
AskUbuntu

The end state I am trying to achieve is such that:

1. Use the router to assign static IPs to the network interfaces or allow the router to manage the DHCP
2. Allow the non WiFi (NICs) to access the network via the wlan0 /eth1 bridge (br0) access point

I found these potential approaches but I am just unclear on what is “current and best practice.”:
Layer 2 AP via ebtables

also
Layer 3 via Proxy ARP

Would appreciate any help or insight.

We don’t have experience in this use-case so it is a bit difficult for us to suggest next. Would need other users to check and provide suggestion.
