My only contact with IPv6 so far has been trying to get port forwarding working with my router at home. Vodafone uses a proxy to tunnel IPv6 to IPv4 to the outs

My only contact with IPv6 so far has been trying to get port forwarding working with my router at home. Vodafone uses a proxy to tunnel IPv6 to IPv4 to the outside, and that proxy does not support port forwarding, since you don't have a unique IPv4 address. After being in contact with Vodafone, it seems like there is no solution that does not cost additional money. It's 2016 btw, wtf

Why do you want port forwarding with IPv6? Or do you want IPv4 port forwarding when your ISP hasn't assigned you an IP. The first shouldn't be required since you would have a public IPv6 address and the second is just a fact of life that we'll have to pay extra if you want a IPv4 address in future.

That would be the same for any carrier grade NAT. If the NAT was just from IPv4 to IPv4, you would have the same problem. Public IPv4 addresses now cost money, so you can't expect to get a public address for free anymore. Of course, with a public address costing around $10 at the moment, it should not add more than $1 or so to your monthly fee.

  > it should not add more than $1 or so to your monthly fee. Quite true. Most hosting companies charge around $1/mo. for a dedicated IPv4. (Naturally, not for shared plans but for VPS/dedicated boxes etc.)

    dedicated IPs for shared hosting is a thing too (commonly needed for SSL virtualhosting when clients don't do SNI)

I thought port forwarding was a thing of the past with IPv6, or am I wrong?

  It is, sounds like he was trying to port-forward for IPv4, but can't as his ISP uses a CGN or 464XLAT or something to provide IPv4 access - so port forwarding isn't an option. All that needs to be done is add the appropriate firewall rules (probably on the router and computer) to allow traffic for that port and it'll be accessible from the outside over IPv6.
