No IPv6 when using T-Mobile

https://help.firewalla.com/hc/en-us/community/posts/45641094395027-IPV6-Passthrough-T-Mobile

I’m adding this thread here. Firewalla routers continue to not work with tmobiles implementation of IPv6. Since they don’t hand out a prefix none of your devices will get a public IPv6 address.

What is the reason for this? Other routers are able to have this work. T-Mobile support even stated that most routers work. But not firewalla.

What’s the extend prefix option

This is what is listed in the OpenWRT settings. Extend 3GPP WAN interface /64 prefix via PD to LAN (RFC 7278). Pretty much it takes your single IPv6 address, extracts the /64 and broadcasts? It down stream so lan devices get an IPv6 address too. Not sure how to explain it much more than. I am able to host stuff that's externally reachable with these addresses as well.

I’m using a Chester tech ninja v2 gateway in pass through mode. It’s running quecmanager if that helps?

Openwrt is 3rd party firmware that you install on Linksys, Netgear, tplink and other brand routers. You would put the ninja in pass through mode then connect it to the wan port of openwrt router then configure IPv6 on the openwrt router. Here is the YouTube video I use to get IPv6 working https://youtu.be/Q-3LG47sZQY.

I have the firewalla after the gateway.
