Does anyone have IPV6 working with the T-Mobile 5G gateway feeding packets to an Asus RT-AC68U router?
I do have this working for IPV4, caveats on double NAT notwithstanding.
Can’t seem to get IPV6 configured properly on the RT-AC68U. “Native” mode doesn’t work at all. “Passthrough” sort of works (devices get addresses via SLAAC) at first, but blows up due to a MTU issue (router bug?).
If you have it working please share how you configured it and what your firmware revision is. Many thanks.
