What's Changed

Fixed

  • **IPv6 delegation now works when the WAN interface holds the delegated block

itself.** Some providers configure the delegated range directly on the WAN interface at its exact size (DigitalOcean assigns its /124 this way), which left the kernel with two equally-specific routes for the block — WAN and tunnel — and the WAN won. Traffic toward device addresses, including replies to connections devices opened, exited the WAN and was lost, so devices had IPv6 addresses but no connectivity. The tunnel now installs an explicit host route per device address, which always takes precedence. Routed prefixes, and on-link blocks configured at a shorter length than the delegated prefix, were unaffected.

  • Port 80 is the HTTP→HTTPS redirect on every public IPv4. Upgrading

re-enables the redirect on every public IPv4 (clearing any per-address opt-outs) and removes any published forward that occupies port 80, so a plain http:// request always bounces to https://. Republish port 80 to a device afterward if you need it there — turn the redirect off for that address first.
