Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

I'm not too familiar with VPNs that offer IPv6 addresses, so I can't help with that. But I'm curious about why some people want IPv6 addresses. Are there any benefits to having an IPv6 address?
I'm not an expert, so somebody may be able to give better responses.
It looks like IPv6 addresses have access to all 65,000 ports, whereas IPv4 addresses need to 'forward' them. I don't know about other VPNs, but the one I'm using only allows forwarding 1 port at a time and I don't get to choose it.
With IPv6, I hope to be able to have multiple ports open to make it easier to host multiple services.
Port forwarding is a function of NAT. It’s only needed because there aren’t enough ipv4 addresses for every device, so in most networks a lot of devices share a single ip and specific ports are forwarded to specific internal hosts
IPv6 has a large enough address space that this isn’t needed. You can still do it if you want. But mostly you just need a firewall without any NAT.
There’s more to it than this but you should get the idea.
That's great and all, but how does it help with VPNs only forwarding one port?
You responded to a question with an incorrect answer. I was correcting that.
VPNs shouldn’t need to forward any ports when using ipv6. They can provide an entire ipv6 subnet to you.
Ok, just making sure.
