Migrating all my IPv4 stuff (firewalls, VPN, routing tables, etc) to IPv6 is probably the one thing I’ve procrastinated for the most time in my life :/
Posted in December of course, after re-enabling IPv4 and restoring their internet connection to a functional state cuz some mystery process didn’t respond all month.
Edit: I actually can’t even access the link at the moment, maybe they forgot and left some IPv6 task enabled.
The challenge didn’t ask to disable ipv4 but it was (jokingly) daring people to expose all ports to public to see how long the system would last before being exploited by bots. It wasn’t meant to be taken seriously 😆
NAT != closing ports
How would you disable NAT and still use ipv4 unless you are able to assign a public IPv4 to your PC (and have nothing else in the network)?
you connect your PC directly out of the link that the ISP is giving you (if allowed), for example via PPPoE
You got it on the nose, only one device.
You can essentially achieve this with some routers with a “DMZ” network segment/ device, so all incoming requests to your external IP get forwarded to it automatically. You don’t even need to disable NAT if you set it up well.
A standard DMZ still does NAT. You get a private IP and the router "nat"s you, just that it forwards all incoming traffic to that device by default. I think technically, that gets you disqualified for no nat november. Though, you’d end up exposing the ports of the machine to incoming traffic, that’s correct.
