I have the latest Voxel firmware loaded into an RBR50 and 2 RBS50s. I am trying to run ProtonVPN directly on the router. I am a bit lost into how to do it.
Is it, taking a USB formatted as ext4 and putting the OpenVPN config file from ProtonVPN in /openvpn-client ?
I'm wondering if I should go back to v31 or v30 so due to random bursts of high CPU usage which was not present before:

This appears to be due to these processes and is also present on v31, anyone have any idea why this runs randomly?

@Voxel and All,
Im a bit confused on netdata. I installed entware and netdata package from Voxel repository. With default config - does it write anything to flash? I hope not...I'm a bit paranoid on this since its very old hardware already. Can you please confirm?
Is it possible to ask it to write data on the same usb drive?
Thank you!
Hi all, a quick message to say thank you for the Voxel firmwares - been using for a while and they certainly run better than with stock firmware. That said, I may be selling mine soon and so would like to revert to stock firmware. Before I stuff anything up can I check whether it straightforward to do that and if I am guessing the right steps, i.e. download latest firmware direct from netgear - upload it to satellite first. Then upload it to main device?
