IPv6 is not working, cannot ping gateway

July 4, 2015 2.4k views
IPv6 Networking

I cannot connect my droplet using IPv6, so I connect it with IPv4, and use ping6 to ping my gateway(2a03:b0c0:1:d0::1) and all the packets are lost.
I can use IPv6 a few days ago, so something under maintenance?

Your gateway works, do you changed some System Configuration regarding Network ?

  • Thank you !
    I re-checked my firewall settings, and found ip6tables DROP all my packets.
    Set to ACCEPT all packets, everything works normal.
