+Subject: wg-quick: freebsd: rebreak interface loopback, while fixing localhost
+
+The commit 7c833642 ("wg-quick: freebsd: allow loopback to work") was
+supposed to make things better, but actually it just started sending
+legitimate localhost traffic over the WireGuard interface, which is
+really quite bad.
+
+This reverts commit 7c833642dfa342218602ab18e7091e86408d2982.
