strange behaviour of IPv6
I have a strange behaviour of the IPv6. My DSL ISP provide native IPv6 support. I connected the amplifi router in a DMZ (my ISP has no bridge support).
The amplifi has IPv6 enabled:
I can see that the machine connecting to it have IPV6 addresses too. But when I connect to https://test-ipv6.com the tests fail but not always. In bridge mode, IPv6 always work however.
Any idea what could be the issue? What should I look?
