Does Shaw with the XB6 modem, or any other, finally offer IPv6 support?
September 2020 Upload Speed Increase Starting September 10th 2020, Fibre+ 150, 300, 750, and Gig will all see a major increase in their upload speeds. Fibre+ 150 will increase to 15 Mbps, Fibre+ 300 to 100 Mbps, Fibre+ 750 to 100 Mbps, and Fibre+ Gig to an amazing 100 Mbps. These updates will happen automatically for eligible customers at no extra cost. From what I can tell, you need to be on a DOCSIS 3.1 modem so if you have a Hitron or Cisco, you won't get it. Grandfathered plans will not be eligible. EXISTING CUSTOMERS will get it at the end of September while while new customers can start getting it now.
I've got all the details posted over on the Shaw Community, but thought I would cross-post here to get a few more eyes on it: https://support.shaw.ca/t5/internet-discussions/xb6-blocking-6in4-ipv6-tunnel/m-p/32143 But the breakdown essentially is: XB6 (CGM4140) seems to not be letting 6in4 (protocol 41) traffic back in. Worked fine on a Hitron CGNM-2250, but not on the CGM4140. Comcast users on a similar sounding platform also reporting this issue: https://forums.businesshelp.comcast.com/t5/Connectivity/IPv6-over-IPv4-6in4-seems-to-be-blocked/td-p/41807. This also sounds somewhat similar to a "VPN blocking" issue with the XB6 from last year: https://www.dslreports.com/forum/r32733051-Shaw-blocking-VPN where it sounds like there were also some stealth firewall rules still in play even in bridge mode that were eventually corrected in a firmware update. Anyway, if anyone else has seen this specific issue, a post over at the Shaw community would be appreciated.
