NAT traversal not needed. Just need to deal with firewalls. So that's one fewer thing to think about when doing peer-to-peer file sharing over the internet.

- ectospheno 1y ago“Just need to deal with firewalls.” The only sane thing to do in a SLAAC setup is block everything. So no, it isn’t a solved problem just because you used ipv6.
- kccqzy 1y agoNo. Here's a simple strategy: the two peers send each other a few packets simultaneously, then the firewall will open because by default almost all firewalls allow response traffic. IPv6 simplifies things because you know exactly what address to send to.
- ectospheno 1y agoThat is my point. You hole punch in that scenario even without NAT. It is no easier.
- the8472 1y agoIt's easier since you don't don't have to deal with symmetric nat, external IP address discovery and port mapping.
