给家中的服务器, 分配 IPv6公网地址

发表于由

条件:

中国电信光猫, Openwrt 路由器, 阿里云域名

Step 1: 路由器升级, 最新版 OpenWrt / 23.05.03

Step 2: 从电信获得 宽带帐号/宽带密码

Step 3: 设置光猫为Bridge 模式

Step 4: 路由器 Lan 接口 IPv4 地址设置为 10.0.0.1

Step 5: 路由器 Wan 接口 修改为 PPPoE 模式, PAP/CHAP username/password 填入从电信获得的　宽带帐号／宽带密码

Step 6: 因为PPPoE 拨号会同时获得 IPv4 和 IPv6地址，wan6 接口没用，删除wan6接口

Step 7: 重起wan接口，会自动拨号，若成功，自动增加wan_6虚拟接口，IPv6 和IPv6-PD

Step 8: 修改Lan接口Advanced Setting：

Delegate IPv6 prefixes = yes

IPv6 assignment length = 60

IPv6 prefix filter = wan_6

Step 9: 修改路由器 network/dhcp/Static Leases, 为每个IPv6公网网卡增加一项纪录：

包括: Hostname, Mac 地址，IPv4，IPv6-Suffix，

为方便记忆，我选择 IPv4 最后一栏与IPv6-Suffix 相同，

比如，mpd IPv4=10.0.0.222, mpd的IPv6-Suffix 设置为0222

Step 10： 根据应用需要，修改基于端口的防火墙：Network/Firewall/TrafficRules 增加纪录

至此，路由器设置完毕

域名更新

由于每次拨号，都会获得一个不同的IPv6-PD值

可以使用脚本程序，监控路由器中的IPv6-PD值，若有变化，调用域名服务商的API接口，更新IPv6值

https://github.com/zhengleic/ddns-aliyun

存在问题：

发现重新拨号，IPv6-PD变化后，应用服务器可以自动获得新的IPv6，并访问外部网络，但无法从外部网络访问应用服务器

原因不详， 应用服务器为Debian 10

解决办法：

更新域名后，同时将应用服务器的网卡down/up一次: ifdown dev / ifup dev

# From web admin portal, setup new wireless wan port for 5G and 2G separately:
# http://192.168.1.1/cgi-bin/luci/
### Network
### Wireless
### Scan
### Selected your existed SSID, Joining Network
### ## Replace wireless configuration  = yes
### ## Create / Assign firewall-zone   = LAN
### Go to Network/Interface
### Set the IP of  wireless wan, as normal

Login into your MPD system, add the following block into the the mpd.conf file:

audio_output {

 type "pulse"

 name " Wifi Router"

 server "IP_OF_WIFI_ROUTER:4713" 

}

Now, you can find the “Wifi Router” option item, from Outputs/Server properties/M.A.L.P, suppose M.A.L.P apk installed android handset
