I have no problem to do ping6 and receive ping6 icmp's, i can see data flowing in my router when someone is pinging my ipv6 number. The problem is that the information under tunnel information at my login page says that i have 100% loss, which sound quite unbelievable when i don't have any problem to ping my self and the PoP and other IPV6 out there in the world. My tunnel is an 6in4-static Configured on a Mikrotik Routerboard RB450 RouterOS 3.13 anyway I provide the information here This is the last day graphs Latency: nan loss%: Min.= 100%, Avg. = 100%, Max. = 100 % Packets/s: Input: Min. = 0.00, Avg. = 663.23m, Max.= 8.99 Packets/s: Output: Min. 728.06m, Avg. = 4.00, Max. = 18.67 Ockets/s: Input: Min. = 0.00, Avg. = 663.23m, Max. = 8.99 Ockets/s: Output: Min. = 0.00, Avg. = 0.00, Max. = 0.00
