Would it be possible for me to make comments to other instances etc?

Solved: I can’t, it would only work with a public domain.

No, ActivityPub is a push protocol. Other instances send data to your instance via HTTPS and only HTTPS. So you need at minimum a public domain and web server with TLS enabled.

Some people use Cloudflare tunnels to avoid opening ports or just get a cheap VPS to forward the traffic home without exposing the home IP.

You do realize all this is easily done with a reverse proxy + DuckDNS?

Wouldn’t you need a publically available IP? DuckDNS is only for dynamic IP’s that is public, yes?

Duckdns is pretty much a service that offers free domain names… that could point to any public IP. (I have seen setups where local IPs are used just for HTTPS). So its good for instances as HTTPS can be achieved without buying domain name.

Works with anything that can open ports. DuckDNS works by pinging their service from anywhere to update the target IP for the subdomain.

Plain HTTP should be considered obsolete. Also it makes impersonating websites harder (but not impossible)

Additionally, HTTPS if very easy to set up nowadays and the certificates are free1.

1: Assuming you have a public domain name, but for ActivityPub that’s already a requirement due to the push nature of the protocol.

Data send via HTTP is not encrypted. That’s bad.

I want it encrypted but I don’t want to ask a 3rd party to get a certificate.
