Clearly we have a lot of IPv6 expertise on here. I probably don’t have enough spare brain capacity to become expert myself, so I’m hoping somebody might be able to comment on a couple of concerns I have.
Iirc, one big win for NAT is that it (accidentally) provides a layer of privacy, as it is hard to associate the public IPv4 addresses with individual devices behind the NAT. IPv6 compensates for that, and even improves upon it, by using IPv6 addresses that change regularly, and are unpredictable. Correct?
Now to my concerns...
1. Is there a point of failure at whatever server assigns these addresses? I’m thinking of my favourite mantra “All software has bugs”. Assuming the IPv6 servers are also buggy, might vulnerabilities emerge that compromise the privacy of address allocation?
2. Will it be possible for future government interference (think RIPA) to mandate that ISPs disclose details that compromise the privacy of IPv6 address allocation?
Genuinely grateful for guidance on these questions.
I’d also be interested in an answer to Alex’s last question so to avoid burying it, I’ll repeat it.
So how exactly do I allow ALL incoming connections to the games consoles on v6 without allowing it for the entire LAN?
