IPv6 connectivity is included, but unfortunately, the only IPv4 connectivity they offer is Carrier Grade NAT, due to the exhaustion of IPv4 addresses in RIPE. I travel a lot, and I've become accustomed to accessing my home network via SSH, VNC, etc. It appears uPNP and PMP are unsupported by CGN. So, without a publicly-routed IPv4 address, I'll be unable to reach devices on my home network from an IPv4-only connection, such as the one provided by my cellular carrier (which also appears to be behind some kind of NAT, by the way). If the ISP isn't willing or able to sell me an IPv4 address, what alternatives do I have? I'd be willing to pay a small monthly fee for, say, a VPN service that would allow me to accept incoming connection requests on a range of ports on their Internet-facing IPv4 address. Does such a service exist?"
You can always get to IPV6 on the out (Score:4, Interesting)
Every system I've seen has some form of IPV6 tunneling that allows you to call out to an IPV6 server. The only time it fails is if you're trying to host an IPV6 server which will fail due to NAT but connecting to an IPV6 always works. The fact that you've got an IPV6 server means you're set. Run Teredo/Miredo on your clients and connect away.
Go setup teredo/miredo and connect away.
Re:Port block allocation & PCP (Score:4, Interesting)
Port control protocol [potaroo.net] is also very close to being reality [cisco.com]. It's a bit like a combination of UPnP and DHCP that allows static IPv4 ports to be requested by and allocated to an end user like IP addresses are now.
Humans' ability to create complex and convoluted workarounds for problems that have been foreseen for 20 years and have had a solution for equally as long simply waiting for a bit of investment in infrastructure amazes me. If people spent even half the amount of effort in implementing IPv6 as they do finding assbackwards workarounds to easily solvable problems then the world would be a much better place.
