Looking for advice on Dual WAN IPv6 not working.

[InductiveSoul]

Hello, I hope this post reaches you at a good time and that your day is going well.

My issue seems a bit silly, but I have II WAN devices with their own IPv4 & IPv6 address.

I have them set up with gateway groups one for IPv4 and the other for IPv6 both set to Priority 1 and 2 respectively preferring Cable internet over LTE Backup. I have been trying to figure this out but, when I have both devices attached the pfSense box only allows one of my IPv6 WAN's to work at a time. I am not sure whats going on. Attached is my main panel, let me know if you want more config info if this is not enough to go off of.

• Thank you for your time.
