Recently, I tried two things with SSLH: using it properly with systemd having it working with both IPv4 and IPv6 (since it runs a machine that supports both) and of course, the firewalling part is now managed with nftables configuration of SSLH itself SSLH is pretty simple: if you tell it listen on a hostname that resolves to both an IPv4 and v6, then, it will work in dual-stack if you tell it to forward request to a hostname that resoves to both an IPv4 and v6, same thing.
