Just how many times do people need to fuck up perfectly well working systems to realise that ChatGPT, no matter the version, is NOT a replacement for doing some basic searches, or asking the community?
LLMs hallucinate. It’s their PRIMARY FUNCTION. DO NOT use them for technical documentation or to answer arbitrary technical questions.
This is a perfect example of such hallucinations. The vb-docker bridge is created so that the containers on the (main) docker network can communicate with each other (Docker by default creates a network for all containers that do not specify a separate network or host mode).
The host, however, will always be able to talk to these devices, as it is part of the network (it essentially acts like the router of your home network). Adding it to br0 is the stupidest idea you can do, and you’re hella lucky you only needed a reboot - it could’ve screwed up your networking settings so bad, you would’ve needed a complete reinstall of TrueNAS just to get things back in order.
Docker already provides a pretty solid networking setup, you don’t need to reinvent the wheel, especially not using ChatGPT. Just RTFM. It’s worth ten times more than the hardware your average ChatGPT instance needs to run on.
