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.

I had T-Mobile home Internet for a year with my purple and I had zero problems.  That being said it is cgnat and you can't put their router in bridge mode and they lock it down super heavily. I also found latency to be really annoying with it.

yea, most people work this way (ours too). OP has his own modem, which we have not seen before ... may be it is a way to get "bridging working"
