The issue is the absence of being able to port forward in a lot of places. UPNP exists on some networks but it's usually disabled. But if we want actual peer to peer we're going to need to implement some way to accept incoming connections EVERYWHERE.
IF ONLY WE COULD USE IPV6 WE WOULDNT BE HAVING THIS PROBLEM
YES FUCK YOU TOO COMCAST.
Gonna be real here, I'm in tech, there is no fucking way I'm gonna open my PC to the entire fucking internet. Vulnerabilities are everywhere and no code is perfect. Firewalls and nat help stop so many attacks from the start.
Even if ipv6 is common I will assume most implementations will be nat based.
You definitely use a firewall, but there's no need for NAT in almost all cases with ipv6. But even with a firewall, p2p becomes easier even if you still have to do firewall hole punching
