. If they're actually friends, they'll know what's false or flatly implausible.
But isn't the point of putting the information up to inform the people that wouldn't know what's false? Making the assumption that putting information up is useful, you're not gaining the use out of that if you put false information up.
You can port forward anything that you want to face the web.
Maybe I can, anyone who's tried to manage p2p connections knows that the general public has a lot of trouble with this or can't do it - sometimes due to multiple layers of NAT. UPnP doesn't help either because it's not enabled.
Personally, I like the added protection of my own router.
You might be interested in the added protection of a firewall then where you could block unsolicited connections.
I said this 15 years ago, and I'll say it again, IPv6 will never fly. Ever. We will all just nat and forget about it.
It's starting to fly already! Lots of ISPs have the equipment when they upgrade and it's a good alternative to multi-level NAT. Sure makes p2p connections easy.
What about a smart fridge that keeps track of what food you have? That'd be useful to access while at the grocery store. (I know, I know...:you damn kids with all your technology..."). There are lots of devices that would be nice to access remotely but can't because of NAT.
Basically if you can port forward, you can configure a firewall in the same way for the technology adverse folk.
Why has people not generally adopted V6 years ago ?
Probably because the hardware in (almost) every routing device needs to be updated to support it. Even if you went with a simple expansion of IPv4 it wouldn't be simple because a router that's looking for a 4 byte address isn't going to know what to do with an 8 byte address. Might as well go with a 16 byte address while we're updating everything.
