IPV6 bridge issue

[mantissa]

 I have a ONT that connects to a router. I have a working IPV6 network until I insert an OPNsense bridge. IPv4 works fine on the Opnsense bridge but I cannot get any GUAs on the router with the bridge in place. I followed all the directions here https://docs.opnsense.org/manual/how-tos/lan_bridge.html but I just cant get an addresses downstream.

All directions meaning the bridge has a link local address too? Double check that.
