      I have three interfaces configured, plus the WAN. I am using one of these interfaces for a guest Wi-Fi VLAN. I am enabling IPv6 support in my network.

      How do I create a rule that allows IPv4+IPv6 traffic from that guest interface to the WAN interface and the wider Internet but not to/from the other interfaces?

      I had rules for IPv4 only based on IPv4 interface subnets but I don't see an equivalent that would work for IPv6 and delegated prefixes.

        Thinking more about it, I think my problem is that I don't know what "interface subnets" means for IPv6.

        Does it mean, "the address of the interface/64", which in my case would be the /56 from my ISP + the prefix configured in pfSense?
