Cannot share internet over usb to rasp zero with RNDIS on mac, when RP is connected I lose internet connection on my mac

Question

I've been trying to connect my raspberry pi zero over the internet with RNDIS on a mac.

And while it seems very easy on every tutorial, it doesn't work for me.

I will share a few screenshots so you can understand my configuration.

So I been able to shh into it and to do some configuration following this tuto

Revisiting the Raspberry Pi Zero WiFi Hacking Gadget

and this one

Turning your Raspberry Pi Zero into a USB Gadget

Because the configuration on tuto didn't work, I started using a different numbers but the idea is the same.

/etc/resolv.conf :

nameserver 8.8.8.8 (also tried with my router address 192.168.0.1)

/etc/network/interfaces :

allow-hotplug usb0
iface usb0 inet static
    address 192.168.0.15
    netmask 255.255.255.0
    network 192.168.0.0
    broadcast 192.168.0.255
    gateway 192.168.0.1

So this is where I am.

As for now, I cannot connect through ssh anymore no idea why. Something I noticed is while I give it a static IP and while I'm being able to ssh into it, I lose my internet connection on my laptop which I find very weird. Isn't is supposed to share internet?

Thanks for your answers

Answer 1

Firstly, undo all your changes to /etc/network/interfaces - if you're making changes here you are following old tutorials (as one of your links suggests) - I wouldn't say never touch anything here, but only do so if you are 100% sure you know what you are doing

Now, edit /etc/dhcpcd.conf and add the following

interface usb0
static ip_address=192.168.0.15/24
static routers=192.168.0.1
static domain_name_servers=8.8.8.8 (or whatever is appropriate to your needs)

This does assume your MAC is set up correctly with IP address 192.168.0.1 for the RNDIS interface - but you've shown nothing regarding that, so I'm speculating that isn't also an issue
