- Dylan16807 2y agoI suppose I can try that some time. I can find absolutely zero mentions of that for the ISP, just the option of buying a static IP.
- kortilla 2y agoNah, many carriers don’t support it. I’ve always had to resort to STUN
- matrix2003 2y agoSTUN also isn’t guaranteed if the router is strict. IPv6 removes a lot of these unknown and strange ways that IPv4 infrastructure can break things.
- kortilla 2y agoYep, my point was just that STUN works far more frequently than explicit port forwarding protocols. Part of the reason (for better or worse) is that most major console networks (Xbox live, PSN, etc) will grade your connection poorly if STUN doesn’t work. Customers who otherwise don’t know about networking do complain to ISPs about this sort of thing.
- orangeboats 2y agoPCP is not widely deployed in South East Asia at the very least. Relying on it is not feasible.
