ddwrt ipv6 支持设置

作者 admin

走了不少弯路。

固件: DD-WRT v3.0-r31205M kongac (02/03/17 v24sp2 应该是这个版本。

网络联通有公网ip

首先去ddwrt官网看配置。

先决条件

DD-WRT兼容的路由器
关于Command Line的知识
关于ip command的知识
DD-WRT version 22 prefinal 5 minimum with distribution voip or standard only
- IPv6不是在所有的DD-WRT v24上都能工作。 24v sp1已经正式可以在IPv6下工作。
通过图形界面 IPv6 Administration/Management/Router Management/Ipv6 启用IPv6
启用jffs 将有所帮助 (可选)

[edit]局域网上的IPv6

[edit]概述

如果你已经有一个工作的IPv6路由器，或者对讲IPv6通信传出局域网不感兴趣，那么你主要关心的是如何将无线客户数据传给有线客户。

如果你的DD-WRT路由器是你的IPv6路由，查看下面的其他6到4隧道解决方案。

[edit]开启IPv6支持

在 Administration>Management 页面，启用 IPv6 和 radvd。

[edit]配置Radvd (如果 DD-WRT 不是你的IPv6路由器)

Radvd与DHCP服务器类似。它将你的IPv6前缀通知给本地网络，以便新的客户机可以生成它自己的IP地址。下面的配置告诉radvd从有线端获取一个IPv6地址，然后适当地播报给LAN (br0).

将下面的代码拷贝到radvd设置框:

interface br0 {
   AdvSendAdvert on;
   prefix 0:0:0:1::/64 {
    AdvOnLink on;
    AdvAutonomous on;
   };
};

[edit]6to4 Setup

[edit]Overview

6to4 is a mechanism which assigns a large block of IPv6 addresses to every IPv4 address on the Internet. You can use 6to4 with DD-WRT to give every computer on your network a globally-accessible IPv6 address without the need to configure explicit tunneling. This should be the simplest method to add IPv6 to your entire network.

Important Reminders 重要事项:

In order to use ipv6, you need the Standard or VoIP version of DD-WRT, as these are currently the only ones which support both IPv6 and radvd. 要使用ipv6，你必须使用Standard 或 VoIP版本的DD-WRT，它们是同时具有IPv6和radvd的版本。
The detailled configuration steps are targeted toward users with a basic DHCP connection for the WAN part. So, if using PPPoE will require replacing vlan1 with ppp0 in each instance. Other connection types will vary. 具体的配置步骤是针对某一个WAN接口以及其下的局域网而言的。因此拥有一个以上WAN接口的路由器，需要针对自己使用PPPoE拨号的具体情况来替换脚本中的vlan1参数。
When using DD-WRT standard on a router with 4MB Flash, there is no space available for jffs. 如果你的路由器使用standard版的DD-WRT或Flash空间只有4MB，将没有足够的空间分配给jffs。
This guide only relies on nvram variables, so that jffs is not needed. 本指南仅依赖于NVRAM，不需要jffs。
The configuration shown below has been verified to work properly on v24 sp1 stable (standard) 下面的配置在v24 sp1(standard版)已可稳定运行

[edit]Enabling IPv6 Support

On the Administration>Management page, enable IPv6 and radvd.

[edit]Configuring Radvd

Radvd is similar to a DHCP server. It advertises your IPv6 prefix to the local network, so that a new client can generate its own IP address. This config tells radvd to get a 6to4 prefix from the WAN side (vlan1) and announce it to the LAN (br0). Radvd类似于一个DHCP服务器。它公布你的IPv6前缀到本地网络，使新的客户端可以生成自己的IP地址。这个配置告诉radvd获得来自WAN端（VLAN1）6to4前缀，并予以公告到LAN（br0）

Copy the following into your radvd settings box:

interface br0 {
   MinRtrAdvInterval 3;
   MaxRtrAdvInterval 10;
   AdvLinkMTU 1280;
   AdvSendAdvert on;
   prefix 0:0:0:1::/64 {
    AdvOnLink on;
    AdvAutonomous on;
    AdvValidLifetime 86400;
    AdvPreferredLifetime 86400;
    Base6to4Interface vlan1;
    AdvRouterAddr on;
   };
};

[edit]Startup Script

This startup script acquires your current IPv4 address and uses it to calculate a 6to4 IPv6 address. It then creates the tunnel interface, configures a route, and assigns the address. Afterwards, it sends radvd a SIGHUP so that it will become aware that the prefix has changed. 该启动脚本获取当前的IPv4地址，并用它来计算的6to4 IPv6地址。然后它创建的隧道接口，配置路由，并分配地址。接着，它发送一个SIGHUP radvd使其意识到，前缀已改变。

Go to Administration>Diagnostics or Administration>Commands in v24 sp1, copy the following into the big box, and hit "Save Startup".

insmod /lib/modules/`uname -r`/ipv6.o
sleep 5
radvd -C /tmp/radvd.conf start
sleep 5
WANIP=$(ip -4 addr show dev vlan1 | awk '/inet / {print $2}' | cut -d/ -f1)
if [ -n "$WANIP" ]
then
 V6PREFIX=$(printf '2002:%02x%02x:%02x%02x' $(echo $WANIP | tr . ' '))
 ip tunnel add tun6to4 mode sit ttl 255 remote any local $WANIP
 ip link set tun6to4 mtu 1280
 ip link set tun6to4 up
 ip addr add $V6PREFIX:0::1/16 dev tun6to4
 ip addr add $V6PREFIX:1::1/64 dev br0
 ip -6 route add 2000::/3 via ::192.88.99.1 dev tun6to4
 kill -HUP $(cat /var/run/radvd.pid)
fi

[edit]6to4 on current builds (after v24 sp1)当前版本的6to4（v24 sp1以后的版本）

Pandora-Box got a script that works on current builds of v24. This has been successfully implemented on Eko 13309 big (which does not come with ipv6, so you must use "ipkg install kmod-ipv6" to get it to work). Pandora-Box有个脚本可在v24版本上运行。这个脚本在Eko 13309 big{某路由器的型号}上使用成功(其中ipv6不能启动，因此必须使用"ipkg install kmod-ipv6"让ipv6运行){貌似是Eko 13309 big才会碰到的情况}

The scripts are as follows:

in Administration, under IPv6/RaDVD config:

 interface br0 { 
 MinRtrAdvInterval 3; 
 MaxRtrAdvInterval 10; 
 AdvLinkMTU 1280; 
 AdvSendAdvert on; 
 prefix 0:0:0:1::/64 { 
 AdvOnLink on; 
 AdvAutonomous on; 
 AdvValidLifetime 86400; 
 AdvPreferredLifetime 86400; 
 Base6to4Interface vlan1; 
 }; 
 };

in Adminstration > Commands, Startup Script:

 insmod /lib/modules/`uname -r`/ipv6.o
 sleep 5 
 radvd -C /tmp/radvd.conf start 
 sleep 5 
 WANIP=$(ip -4 addr show dev vlan1 | grep 'inet ' | awk '{print $2}' | cut -d/ -f1) 
 if [ -n "$WANIP" ] 
 then 
 V6PREFIX=$(printf '2002:%02x%02x:%02x%02x' $(echo $WANIP | tr . ' ')) 
 ip tunnel add tun6to4 mode sit ttl 255 remote any local $WANIP 
 ip link set tun6to4 mtu 1280 
 ip link set tun6to4 up 
 ip addr add $V6PREFIX:0::1/16 dev tun6to4 
 ip addr add $V6PREFIX:1::1/64 dev br0 
 ip -6 route add 2000::/3 via ::192.88.99.1 dev tun6to4 
 kill -HUP $(cat /var/run/radvd.pid) 
 fi 
 radvd -C /tmp/radvd.conf start

以上方法可以看到ipv6的地址也获取了。但是只有路由器获取。

不过也可能是win7的这个服务没有打开。

google 发现台湾有的人这么设置很简单 ddwrt ipv6
