This guide might be a bit too complicated. If you know of any easier ways to do these things then please let me know.

Oh, I was wondering why this got so long, since it's the same ac connecting with a cable, and then it struck me: others are probably connecting the Ethernet cable to a switch, and not directly to the workstation.

Here's how I do it on the host, for both USB and Ethernet (Plasma):

1. Open network center and add a new connection
2. Select a wired, shared connection
3. Select the usb interface by guessing (enpXsXXuX is likely USB, it will change based on port; enpXsX is PCI)
4. Autoconnect is handy
5. Manual connect available in the network popup

The dev kit will have an ipv4 address in the 10.42.0.0/24 range.

This takes care of IPv4 forwarding too. I'm not sure about IPv6, investigating.

EDIT: I don't seem to have IPv6 here :< It's probably going to be faster for someone else to try to figure this out.

Here's the details of the connection I'm using, obtained with

nmcli connection show "n900 shared"

n900_conn

Ah, I needed to (re)install the plasma-nm package to get the settings module you used.

I tried the nm-tray package to get something to automatically manage the connection via a panel applet. This also seems to work.

I guess I should try some solutions under GNOME.

I wanted to add a reference to a ticket I just filed that demonstrates the relatively easy but not-yet-working procedure to share a connection over the Librem 5 Wi-Fi Hotspot inside Settings: gnome-control-center#107
