我已经尝试在我的 proxmox 服务器上配置 ipv6 大约一个小时了，但我似乎无法正确配置。
/etc/网络/接口：
auto lo
iface lo inet loopback
auto vmbr0
iface vmbr0 inet static
address xxx.xxx.xxx.2
netmask 255.255.255.0
gateway xxx.xxx.xxx.1
bridge_ports eth2
bridge_stp off
bridge_fd 0
iface vmbr0 inet6 static
address 2604:xxxx:xxxx:xxxx:0000:0000:0000:0002
netmask 64
gateway 2604:xxxx:xxxx:xxxx:0000:0000:0000:0001
ip -6 路由

将不胜感激可以提供的任何帮助。这可能很简单，但我对 debian 有点陌生。
