Please anyone could give me some hints to find out the problems. Thanks! Being a novice user, don't know how-tos, need help to troubleshoot no ipv6 traffic after setup & running OK for several months. Noticed no able to connect to "https://ipv6.google.com" ; not support ipv6 while tested at www.kame.net 6 items shown in below are some information off-hand. I don't have enough knowledge to proceed others , Please kindly advise.
