pfSense box cannot access anything over ipv6, LAN clients can

Hello!

Recently I was looking into my DNS configuration and was noticing that my IPv6 only DNS servers were not being accessed. While I can access anything over IPv6 in the LAN, I cannot access anything over IPv6 on the router itself. I already checked my IPv6 gateway and manually set it properly.

Other thing of note: I am using pfatt to connect to AT&T's network, which uses netgraph among other things to trick the AT&T provided gateway into authenticating with the other AT&T equipment. You can find it at https://github.com/monkwho/pfatt.

My ISP (AT&T Fiber) hands me a /60 PD. I have it split up between a LAN and a guest network, each having a /64. My firewall/NAT setup is default except for a port forward rule or two I enable occasionally for school.

Does anyone have any advice on what might be going wrong here?

Thanks so much in advance!

On WAN interface check "Only request an IPv6 prefix, do not request an IPv6 address".

ATT doesn't provide a routable IP to the interface.

That was exactly what I needed. Thank you so much!
