Ah yes, network configuration by way of executing a random bash script from a blog. With tasty morsels like:

># I have to admit, I do not understand ARP and IP forwarding enough to explain exactly what is happening here.

I mean, the number of people on this site who could intelligently explain ARP and IP forwarding in detail is probably 10x higher than in the general population—and that percentage here is probably in the low single digits.

I think you mean the proportion is higher here, unless you mean that >90% of people who could intelligently explain ARP and IP forwarding are HN posters.

Yes, I read it and found the overall approach a bit strange. I wondered why they weren't just using a normal bridge interface, like https://unix.stackexchange.com/questions/363332/how-do-i-con...

Yeah, I don't like the style of this 'first, download this script; then, execute it'.. and it creates/overwrites files.

Why not tell me to create the necessary files, with some article content around what we're doing and why?

As an article this doesn't seem to offer anything more than a suggestively named GitHub repository with a small readme.
