@harald As I understand ndp-proxy, it passes messages across the network, spreading SLAAC addresses from the same prefix over both links. That *would* work routing-wise, but it would make the setup a bit more tightly-coupled than I like. I don't know if I want to marry those networks forever […]

@etam How fast is it compared to stock firmware? I did the same but now it's 3-10 times as slow, barely useable. (If you include random turning off, not useable.) I wonder if it has anything to do with the SD card I'm using.

A circuit board with a smaller board soldered on in the center. The smaller board is covered with gray metal and says ESPRESSIF. Golden, and it has no solder mask. It's all scratched and with splotches of solder around. A resistor is standing on its side. There is a USB port and several free cables attached to spots on the other side. One soldered directly on another component.
