IPV6 Message

When I do the comcast test IPv6 Test only on my PC I get the message below. Do I have change something in Norton?

 

Danger! IPv6 sorta works - however, large packets appear to fail, giving the appearance of a broken website. If a publisher publishes to IPv6, you will believe their web site to be broken. Ask your ISP about MTU issues; possibly with your tunnel. Check your firewall to make sure that ICMPv6 messages are allowed (in particular, Type 2 or Packet Too Big). [more info]

Is this comcast website still active?

http://www.test-ipv6.com/

 

When I test my IPv6 I get this message but other IPv6 Test sites say I'm using IPv6 even the comcast Speed Test shows my IPv6 speed.

Thanks Robert, Thought Comcast ran site. When I clicked your Link you provided still received same error only on my PC not using my Samsung phone internet browser. Thinking maybe my Norton is causing somekind of Firewall error.
