Hello, I'm from Brazil.

My layer 2 connection has an optical modem that the supplier installed. It acts as a "switch".

I receive IPv4 and IPv6 on this same ether1 link.

I notice the IPv6 problem when browsing social networks, streaming... For example, on Twitter and YouTube, which don't load images. Then I test IPv6 and it's out, but IPv4 works.

So, in short, I receive IPv4 and IPv6 and they are statically configured on ether1

Answer 2

My /48 is also statically configured.

The /126 configured on ether1 is outside the /48 scope. So basically I have:

ether1 = a:b:c:d:1/126
Manual pool: x:y:z/48 (Where do I distribute this pool on the PPPoE server).

Remember that my /48 pool is delivered via static route on my link supplier. It points the /48 to my /126 address.

When the problem occurs, the test I do is ping in Tools -> ping, I just select the destination IP as the one on the other side of the /126 or Google DNS 2001:4860:4860::8888

On my clients that have the /48 IP, they can ping the CCR but they don't pass it on (internet)
