Hi, I've an VPS whose network is configered with systemd-networkd. The original interface is eth0 configured by eth0-dhcp.network and has an IPv6 address, which however cannot connect to the HE IPv6 network[1]. So I use tunnel broker to get another IPv6 address. I configured this according to [2]. The new IPv6 address works fine. However, the original IPv6 address doesn't work anymore. When I try to connect to my box using the original IPv6 address, I cannot get a response. Is this related to the ``Tunnel=he-ipv6`` line I wrote to eth0-dhcp.network file? How can I solve this problem so that I can have two IPv6 addresses for different uses? Thanks. Iru [1] https://www.bdwm.net/v2/jump-to.php?url=http%3A%2F%2Fadminhacks.com%2Fbroken...
