Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding. Plz fix!

I just want to use IPv6 passthrough (bridge mode) so I can connect my external router. I don't need port forwarding or inbound access. I called before ordering the service and they told me this was possible - but I guess they lied.

Front-line support are mostly useless and don’t even know about double-NAT and why it is a problem for VOIP and many other apps.

Does T-Mobile have any real network engineers? It seems like the people on this forum are better qualified.

IPv6 passthrough with your router should be working.  It does for me.  But, that's a function of your router. If its not working, the issue is on the inside of your network.  Its not with the gateway.  But, if your VOIP service doesn't support IPv6, using passthrough won't help.  Also, I don't have an issues with VOIP services.  In the past, I have heard of others having issues.  But, I do not.
