Isp started using teredo, how to use ipv6?

[xbipin]

im a beginner in ipv6, just now i noticed my isp defaults to ipv4 but started using teredo at their end for ipv6 so what do we need to configure in pfsense so lan clients can access ipv6 sites.
i currently use ipv4 on lan and NAT.
do we need to configure pfsense differently when isp uses teredo or only when they start using ipv6 natively?

strange thing is when the pppoe session is initiated, i get a ipv4 ip/dns/gateway but i only get a ipv6 default gateway

pfSense doesn't have to know or care about Teredo, the local clients would connect to Teredo directly, all pfSense would see is the IPv4 traffic it uses for tunneling.

but i tried few ipv6 sites and they open from firefox and not from chrome as well as i dont have ipv6 enabled on the client machine nor the teredo adapter

im a little confused, teredo is something windows uses to connect to microsoft servers to connect to ipv6 networks hence i was seeing teredo enabled on my isp.
what i do is connect with pppoe to my isp which provides ipv4 ip/dns/gateway but i see the push this also

the xx:xxxx is the last 3 blocks of my lan mac id of pfsense.

now what i dont understand is does this mean isp is using ipv6 natively or something else?
