can you ping 2001:6f8:306::1 from 2001:6f8:306::11, then can you ping 2001:6f8:202:202::2.

if not look at ip -6 r g 2001:6f8:202:202::2 see what is says

try the reverse ping 2001:6f8:306::11 from 2001:6f8:306::1.

Also have you turned on ipv6 forwarding ? sudo sysctl -a | grep ipv6

also maybe check ip6tables -nvL
