netplan我无法在 Ubuntu 18.04.2 系统上配置默认路由。ip -6 route add ...当发出明确的命令时，该路线起作用。

隐私扩展已被禁用：/etc/sysctl.d/10-ipv6-privacy.conf

net.ipv6.conf.all.use_tempaddr = 0
net.ipv6.conf.default.use_tempaddr = 0
net.ipv6.conf.ens192.use_tempaddr = 0

SLACC 和 RA 已禁用，IPv4/IPv6 转发为一（机器用作 OpenVPN 服务器）

/etc/sysctl.d/10-ipv6-router.conf

net.ipv6.conf.default.autoconf = 0
net.ipv6.conf.all.accept_ra = 0

net.ipv6.conf.all.proxy_ndp = 1

/etc/sysctl.conf

net.ipv4.ip_forward=1
...
net.ipv6.conf.all.forwarding=1

/etc/netplan/01-netcfg.yaml

network:
  version: 2
  renderer: networkd
  ethernets:
    ens18:
      dhcp4: no
      addresses:
        - a.b.c.d/24
      gateway4: a.b.c.e

      dhcp6: no
      accept-ra: no
      addresses:
        - "2001:0db8:0004:4a1a::dead:beef/64"
      gateway6: "2001:0db8:0004::0001"

    ens19:
      dhcp6: no
      accept-ra: no
      addresses:
        - "2001:0db8:0004:4a1a::dead:dead/64"
      gateway6: "2001:0db8:0004::0001"

这会将地址分配给接口，如下所示：

$ ip …
