@JKnott said in Configure IPv6:
Is your ISP's router in bridge mode? That's what you need for IPv6 to be passed on to your LAN.
My ISP router is a router, and can't be converted in a bridging device
My ISP abandoned the bridging mode years ago, I wish it was still possible, it would simply things for sure. The ISP box is, of course, internally, bridging (I guess), but that aspect of the box isn't under my control anymore.
The four big ISPs here, in France - that's Europe, (Orange, Free, SFR, and Bouygues), making up 90+% (60 million ?) of all SoHo Internet connections all have routers these days.
Other countries around me : same thing.
I could, technically, use bridging, which means I could (have to !) ditch my ISP router all together.
Initially, I would loose the triple play concept, as I would have "Internet" (IPv4 and Ipv6) but no more phone, no more video (TV) support that also comes with the box. That wouldn't be to bad for me, as I don't use them.
Most would not agree here I think, as for some reason people still stay hours a day on the box-phone (comparable ancient POTS), and even more behind the TV ...
In my case (France, Orange, Livebox) this means I have to apply what I call Pure Networking Rocket Science to make also the TV and phone to work.
In my case, my ISP box has a DHCP4v server (of course) and a DHCPv6 server that can give a LAN IPv6 that becomes the pfSense WAN IPv6, and - most important, and this does not have a IPv4 counterpart - a - at east one - so called IPv6 "prefix" that will be used for the pfSense LAN.
My DHCPv6 ISP server gets its IPv6 'needs' : an entire so called /48 from the more upstream 'main' ISP DHCPv6 server (I guess) :

oh .... as said above, my ISP does things differently. It's not the standard /48 but a small /56. That's still 256 (minus 1 or 2) network blocks of /64. Ok for now for me, as I don't see how my 4100 can handle that much LAN's anyway 😊
And @Danil-0 Danil, don't worry, as soon as your IPv6 works, you can (nearly) forget about it, as it will be as before : pure plug and play. These days, I don't care or look (less) if traffic uses IPpv6 or IPv4.
This forum uses only IPv6 - if you have it. if not, IPv4 is still very fine also.
