刷机

OpenWRT 18.06 for ZBT WG3526

配置

/etc/config/dhcp

config dhcp 'lan'
     ...
    option dhcpv6 'server'
    option ra 'server'
复制代码

dchpv6和ra配置,保持不变,均为'server'

/etc/config/firewall

config defaults
    ...
    # Uncomment this line to disable ipv6 rules
    option disable_ipv6     1
复制代码

关闭IPV6防火墙，否则本机的一些端口无法暴露到公网

/etc/config/network

关闭global prefix

#config globals 'globals'
#   option ula_prefix 'fdca:59d7:4008::/48'
复制代码

配置pppoe(加自动ipv6)

config interface 'wan'
    option ifname 'eth0.2'
    option proto 'pppoe'
    option username '...'
    option password '...'
    option ipv6 'auto'
复制代码

关闭wan6

#config interface 'wan6'
#       option ifname 'eth0.2'
#       option proto 'dhcpv6
复制代码
