IPv6-Support (ferm / iptables)

Running a Trellis-project on v1.23.0 and am having trouble regarding the IPv6-connectivity – I couldn’t find anything with regards to IPv6-support in the docs or here on the Discourse, only much older posts where it is stated that support is not available…?

Checking the entries for ip6tables-legacy I can see that there is a default DROP policy on INPUT, and there’s no rule allowing TCP port 443. Only port 22 (SSH) is allowed.

I was naiively thinking that this would be handled by default via Trellis and re-provisioning would “fix” any older setup / config-rules.

My questions would be:

  • Does Trellis support IPv6 by default? Since when?
  • What could be the issue for my project not being correctly configured?

Thanks a lot for chipping in…!

Some additional info (AAAA-records verified):

  • I have a project running on Trellis >= 1.23.0 & Ubuntu 22.04.5 which is available via IPv6
  • Another project running on Trellis >= 1.22.1 & Ubuntu 22.04.5 is not available via IPv6
  • Yet another project running on Trellis >= 1.23.0 & Ubuntu 24.04.3 is also not available via IPv6

So there is no real pattern to be made out here and running a diff of the projects doesn’t yield any clues to me…
