  • Unfortunately many of the routers provided by ISPs I have seen where not configured that way by default. They only used NAT as firewall, so without configured port forwarding nothing could be reached with IPv4. But for IPv6: If you know the IPv6 for any system on the local network it is free available on all ports. It is the first thing I check when someone asks me to check their network or configure their internet, and only Fritz!Box have a sane default for IPv6 (but to be honest my other experiences are mostly with shitty Vodafone and german Telekom routers so it is a very limited set, and I really hope that most others are better.)
