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.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

hi everyone,

I was just about to self-host a Ghost blog but then was warned that my ISP might change my external IP address at any time, so I would need to pay for a static IP address.

Is that true?

(I'd not seen much about that in stuff I've looked up so far about self hosting)

You can't port-forward if you sit behind a nat.

Port forwarding was invented for exactly that

Hou will you configure the ISP's NAT router to port-forward? You won't be able to reach the forwarded port if your ISP doesn't foward the port as well.

You can't, this guy doesn't know what he's taking about.

Port forward behind CGNAT won't get you out. Best bet here would be ipv6.

Tor would work. However, only over Tor obviously.
