Raspberry Pi (Debian Bookworm) USB Server

[ReivaXVrai]

I'm trying to setup my Raspberry Pi 3 as a USB server over Wi-Fi as an ad-hoc network using Virtual Here. I have succeeded in getting it to work over my local network, but as soon as I create an Ad-Hoc network on the Pi and connect to it with my laptop, it can no longer connect to the server on the Pi. I have allowed TCP 7575 and UPD 5353 through my firewall, and I have set a static IP on the Pi using nmtui, but so far no luck. Not sure what I'm missing, or if Windows 10/11 are the issue.

Why do you want to set up an ad hoc network? What is the use case..?

My goal is to have the Pi sit in my car with my ECU plugged into it. Then, I can remote access the ECU via WiFi using the Pi and tune the car from inside my trailer.

What an interesting use case, that’s a cool idea. 
 

I have never tried to create an ad hoc network, nor used or heard of virtual here. But you will need to make sure you are exposing whatever webUI’s/services over the ad hoc interface you set up. 
 

There are A LOT of tutorials and YouTube videos on turning a pi into a WiFi router, you effectively want to do that here. I personally don’t know enough to walk you through how to do what you are after, hopefully someone else jumps in who can help or point you to a specific tutorial. I tried googling “r pi travel router plex media server” and such to see how folks are setting up a basic travel router and exposing something popular like plex, but I didn’t quickly see much. 
 

But assuming you can successfully connect to the ad hoc network, the only missing part is exposing the needed services over the required interface.

How would I go about exposing the webUIs/services over ad-hoc?

That’s the part I’m not sure about. But hopefully that will be helpful enough info to point you towards the research you need to do. Or hopefully someone else jumps in on this thread.

How are you doing your "ad-hoc" network? That's an ancient thing that's been deprecated for more than a decade, you can just create an AP now.

 

Maybe easier if you do it the other way, turn on hotspot on your laptop, and connect the pi to it. Whenever you want to use the thing turn on hotspot. Also avoids the Pi broadcasting an AP all the time.

I setup the ad-hoc through the network manager with nmtui. I tried setting it up as an access point, and I had the same issue. The only way it works is on an actual network with access to the internet.
