    Off the top of my head, why did you set the prefix to 0x1? I was under the impression that it only needs to be set if there are multiple vlans

    I have multiple VLANs, 0x1 is my LAN and 0x10 is my DMZ for example. I then get IP addresses abcd:abcd:a01::abcd in my LAN and abcd:abcd:a10::bcdf in my DMZ.

    However, I get a /56 from my ISP wich gets subnetted into /64. I heard it’s not ideal to subnet a /64 but you might want to double check what you really got.

    what are your rules for the WAN side of the firewall?

    Only IPv4 + IPv6 ICMP, the normal NAT rules for IPv4 and the same rules for IPv6 but as regular rule instead of NAT rule.

    My LAN interface is only getting an LLA so maybe it’s being blocked from communicating with the ISP router.

    If you enable DHCPv6 in your network your firewall should be the one to hand out IP addresses, your ISP assigns your OPNsense the prefix and your OPNsense then subnets them into smaller chunks for your internal networks.

    It is possible to do it without DHCPv6 but I didn’t read into it yet since DHCPv6 does exactly what I want it to do.

    I’m no expert on IPv6 but here’s how I did it on my OPNsense box:

    • Activate IPv6 on your WAN interface (probably already done)
    • Activate IPv6 on the LAN interface, use Track interface on IPv6, track the WAN interface and choose a prefix ID like 0x1
    • Activate DHCPv6 under Services -> ISC DHCPv6 for your LAN interface (you can shorten the range like ::eeee to ::ffff, you don’t have to type the full IP)
    • Activate Router advertisments under Services -> Router Advertisments for your LAN interface (set Advertisments to Managed and Priority to High

    After that your DHCP server should serve public IPv6 addresses inside of your prefix and clients should be able to connect to the internet.

    A few notes:

    • Don’t forget to add an allow rule for IPv6 on your LAN as well if you only have one for IPv4
    • Repeat the steps above for every VLAN you have, always use a different prefix ID
    • You don’t have to use NAT rules with IPv6 anymore and can just directly add a regular firewall rule to WAN with the target IP and port and you are done
    • Make sure you don’t have any of the various “Disable IPv6” toggles enabled, there’s a few in the firewall settings and general settings for example


  • Separating the artist from the art is fine for me as long as you don’t support them. There is nothing inherently wrong with consuming media you like from a controversial figure.

    Of course it’s hard to separate the artist and the art if you actively give them money for it.

    I like some of Kanye West’s music but I would never spend a single cent on one of his albums, watch an ad on Youtube for his music videos or listen to his songs on streaming services.







  • I don’t run Pi-hole but quickly peeking into the container (docker run -it --rm --entrypoint /bin/sh pihole/pihole:latest) the folder and files belong to root with the permissions being 755 for the folder and 644 for the files.

    chmod 700 most likely killed Pi-hole because a service that is not running as root will be accessing those config files and you removed their read access.

    Also, I’m with the guys above. Never chmod 777 anything, period. In 99.9% of cases there’s a better way.
