Hi Piotr,
You have to configure your if with a /56 mask and then you will be able reach the ipv6 gateway. Remember to accord your pf rules to allow required icmpv6 types.

What I get from the ISP is the /64 address pool. OVH requires static configuration with gateway outside of the assigned subnet. According to their docummentation: The default gateway for your IPv6 block (IPv6_GATEWAY) is always xxxx.xxxx.xxxx.xxFF:FF:FF:FF:FF. For example: The IPv6 address of the server is 2607:5300:60:62ac::/64. The IPv6_GATEWAY will therefore be 2607:5300:60:62FF:FF:FF:FF:FF. My problem is how to properly configure the route to their gateway. I'm trying i.e.: ifconfig ix0 inet6 alias 2607:5300:60:62ac:: prefixlen 64 route add -inet6 -host 2607:5300:60:62FF:FF:FF:FF:FF -llinfo \ -link -iface ix0 but it doesn't work: ping6 2607:5300:60:62FF:FF:FF:FF:FF ping6: sendmsg: Invalid argument I know, that if I shrink the prefix to 56, the gateway starts to be directly reachable and then it responds to pings. I just wonder if there is a way to make the gateway reachable with proper prefix on the interface.
