I've been using Shorewall for years. I only just now learned that:
https://sourceforge.net/p/shorewall/mailman/message/36589782/

We have 5.2.7. So I suppose someone has picked up the responsibility,
though I do not know who. I certainly hope that Shorewall will continue
to be developed. I find it's interface is unrivaled and could not
imagine working without it.
