I do exactly that, enable nesting in the lxc container, install docker and go from there. It works great

The simplest way is via the F1 Tv app. They have races going back to the 70s. There are also torrent collections that have old seasons, and free streaming sites but I haven’t checked the rules to see if mentioning them is allowed here

I’m currently rewatching 2010 during the break and there were a couple that definitely match your description. That was the last Bridgestone year so it’s interesting to see the difference.

New fans would do well to check out some of the older seasons and compare to modern f1. 2005 and 2009 are personal favorites

I solved the same problem you’re having with Cloudflare tunnels. I added a tunnel to my docker/portainer host and then added services via that tunnel. I did buy a domain name through them to facilitate, but worth it imo. Vastly simpler than dealing with port forwarding and all the fun stuff you need to do with your router. Hope this helps

Edit:wrote this before reading your last line. Cloudflare tunnels simplify the process of dynamic dns, port forwarding, and https on apps that don’t support it.
