Hello, I have an issue where I can't access my ipv6 WAN address externally. I have verizon FIOS, they don't provide me with a WAN address so I'm using the new WAN track interface ability to assign it out of the /56 verizon gives me. This works and the WAN assigns itself an address and I can even ping that address from inside my network, however when I try to ping that address from outside or connect to the wireguard instance running on it, I get no reply. I have a firewall rule passing all ipv6 ICMP traffic externally and I can successfully ping my LAN ipv6 interface address from externally, so the rule is working, I don't get why its not working specifically for my new WAN address.
Second screenshot because they both wouldn't fit on one post
Hey did you ever figure this out? Seeing something very similar on Comcast/Xfinity. Getting assigned a IPv6 address on the WAN interface that I can ping from OPNsense itself, but that I can't ping from anywhere else on the Internet despite having appropriately-permissive firewall rules.
