I don't think even ipv6 without nat would guarantee 100% (not that we can count on ipv6 coverage in the next decade anyway). 1. Stateful IPV6 firewalls still need hole punching to connect peers, thus a stun server.
2. Think about a corporate network with complex routes and potentially multiple firewalls (for load balancing or route optimization). No guarantee you use the same gateway to get to the stun server and the other peer. Thus, punching fails. At least that's my uneducated guess. PS there's nat for ipv6 too (linux supports it). Misery is not going to end. |
