我有一个Sokeris有8个接口：em0连接到桥路由器（ISP）和EM2连接到我的DMZnetworking（networking服务器）。 我从我的ISP a / 56前缀和2个DNS IP，但没有网关IP。
– 问题 –
我的em0没有得到一个公共的IPv6（只有本地链接）。
– 故障排除 –
我在网上search，发现： – OBSD 5.7已经不再需要rtsol，因为它已经包含在内核中。 – 要使用路由器通告，必须禁用IPv6转发。 （这将导致问题，因为我必须在em2和em0之间转发IPv6，以便客户访问Web服务器）
tcpdump的输出如下：tcpdump -vvnli em0 icmp6

有人遇到同样的问题？ 它可能与广泛的DHCP客户端工作，但它应该开箱即用。
谢谢！
