Re:Tell HN: IPv6-only still pretty much unusable

Home routers often greatly simplify the interface.
BT, one of the largest ISP's in the UK, only allow the configuration of destination IP and external/internal ports[0].
I've never expected my NAT to do anything other than map ports. I can see why the ability to map source IPs to different ports would be useful but relying on that as a security feature feels like a foot-gun. I wouldn't feel comfortable exposing an application that doesn't have some form of authentication and/or blacklisting.
