Hole punching, which has various forms, may or may not work.
This means if you're doing something realtime, you may need to stick a server(reachable endpoint) in between it, at the very least reducing performance.
- LoganDark 6mo agoI have never seen any situation where this is not already necessary other than UPnP which already almost never works reliably. A publicly-addressable relay is already practically non-negotiable for anything over the internet.
- lern_too_spel 6mo agoIPv6 everywhere makes that not necessary, which is what the author is pushing for.
- lmm 6mo agouPnP works fine though? What was the problem you had with it?
- LoganDark 6mo agoFor one, monopolies disabling it by default on their equipment? I remember some years ago having to guess the admin password at a vacation house so I could enable UPnP. It's usually framed as a security vulnerability, even.
- vel0city 6mo agouPnP fails when multiple devices are fighting over the same port assignments. uPnP fails when people have it disabled, as has been recommended many times over the years.
- direwolf20 6mo agoWithout NAT, it wouldn't be. That's the point.
