Networking challenge

[astral wedge]

So, my understanding is clear for this problem

But I want to discuss the approach the steps one can follow to such questions

My approach - first I will check for the network setup for both client and server. They are able to communicate then they should have correct config.

second - wireguard setup check on server and then on client

third- setting up wireguard over pv6, then How can I block the existing pv6 connection? Firewalls ?

Can I try this issue by making such senario

?

I am going to recreate the same on docker, but still thinking at what point they can create the issue that one needs to think about and fix. Can someone suggest what those points can be?

It says right there 6pn not pv6 .

third- setting up wireguard over pv6, then How can I block the existing pv6 connection? Firewalls ?

Again the clue is right there on the "challenge" page:-

You'll need to configure firewall rules to block traffic on the 6pn interface and allow traffic on the WireGuard interface.

my mistake over pv6, and this description is generated by ChatGPT, in the original it is not mentioned

That was too large so I am using it
