Yes, The Book of PF, 4th Edition Is Coming Soon https://nxdomain.no/~peter/yes_the_book_of_pf_4th_ed_is_coming.html

Long rumored and eagerly anticipated by some, the fourth edition of The Book of PF is now available for preorder https://nostarch.com/book-of-pf-4th-edition #openbsd #pf #packetfilter #freebsd #networking #security #tcpip #ipv6 #ipv4 #bookofpf

... and of course somebody had to ask, "when can we expect a fifth edition", to which the answer was "let's get this one out the door first"

That said, watch this space for further announcements!

If you're not running your own DNS resolver, and/or not running PiHole, changing your DNS from 8.8.8.8 to 9.9.9.9 is a good first step

Friends, I have a problem with the ISP that operates the fiber line to our house.

Pretty much every time they need to reconfigure their CGNAT they for some reason kill IPv6 and our autoconfig'd gear end up with "Unique Local" (fc/7) addresses.

Is this a common problem, seen elsewhere?

I suspect Cisco gear but have no way to check.
