IPv6

I noticed by accident that in my home network IPv6 is not functional, so I decided to fix that, and started studying about IPv6.

I have an opnSense firewall which connect to my ISP port as WAN, and then the LAN. The point is that o do not get a GUA on my WAN, but I get it if I connect directly a pc to the ISP port....

The opnSense seems to be configured properly, and the ISP itself do provide IPv6 as I can get a GUA address when I connect my Linux laptop to the ISP router, so I am not sure...

Anybody has any hints?
