In the past, until about a month ago, with IPv6 enabled on my router and set to "6rd Tunnel", I was able to access v6 sites with Videotron. A test of my connectivity using test-ipv6.com gave me a perfect score of 10/10. Now, with no changes to my network setup, outside v6 connectivity is not working at all.
Has anyone else experienced the same problem? Does anyone have IPv6 connectivity with Videotron?
