Announced IPV6 through firewall Linux

confused123

I'm pretty baffled by this one, when using ipleak.net every test except for the torrent test will pass. It will return 

IP: <PIA IP ADDR>, Port: <some Port> , Annonced IPV6: <My Real IPV6 ADDR>

I have a very basic ip6tables firewall

$ ip6tables -L -v
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         
   19  1988 DROP       all      any    any     anywhere             anywhere           

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         
    0     0 DROP       all      any    any     anywhere             anywhere            

Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination         
   12   990 DROP       all      any    any     anywhere             anywhere 

The ip6tables appears to be working, how could my ipv6 possibly be going through? Why can it leak only through a torrent check?

That is curious, the VPN will block ipv6, but the torrent client may be getting it right from the adapter or the router.
