ipv6上不了了 #17

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
我是个新手，请指教
db120-wg刷了ipv6固件，在朋友那可以上ipv6，但是拿到我这就不�
��了。在他那添加了ipv6 
gateway：fc00:0101:0101::1/64，然后修改rc.local中的eth1.1为eth0，其��
�的ip都是学校的静态ip，重启后可以上ipv6.
但是到我这以后只修改了ipv4的静态ip，但是怎么也上不了ipv6�
��怎么回事，请指教

补充，到我这改ip之后，ipv4也上不了了，提示DNS服务器出错

rc.local

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
sysctl -w net.ipv6.conf.br-lan.forwarding=1
ip6tables -A INPUT -p icmpv6 -m mac --mac-source "00:17:59:80:74:10" -j DROP
radvd
ifconfig eth1.1 down
ifconfig eth1.1 up
insmod /nat66/napt66_bcm63xx.ko wan_if=eth1.1
udhcpc -i eth1.1
exit 0

这样话可以上ipv4

但是把eth1.1改为eth0后都上不了了

你是双栈的还是隧道的啊·

从你的ifconfig输出结果来看，WAN口应该是eth0。请把配置文件��
�所有的eth1.1都改成eth0。
网络问题请检查ip -6 route。

不知道配置文件有哪些呢？rc.local这个，还有其他的么？

这时我ip -6 route的结果，请帮忙看看

root@OpenWrt:~# ip -6 route
2001:da8:5000:1405::/64 dev eth0  proto kernel  metric 256  expires 2592187sec 
mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev br-lan  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0

我把rc.local中的eth1.1改为eth0后，就上不了网了
把它改回来ipv4就又可以了，不知道怎么回事？

改为eth0后上不了网，请检查ip 
route，看有无正确的默认路由。

# ifconfig eth1.1 down
# ifconfig eth1.1 up
将接口down再up是为了清空接口的网络配置。如果网络配置没��
�问题就不需要这步。
# udhcpc -i eth1.1
udhcpc可更新接口的IPv4地址和IPv4路由信息。如果网络配置没有
问题就不需要这步。

可以试试下面的启动脚本/etc/rc.local先，不行的话再根据上面�
��两条信息灵活配置吧。

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
sysctl -w net.ipv6.conf.br-lan.forwarding=1
ip6tables -A INPUT -p icmpv6 -m mac --mac-source "00:17:59:80:74:10" -j DROP
radvd
insmod /nat66/napt66_bcm63xx.ko wan_if=eth0
exit 0

# ifconfig eth1.1 down
# ifconfig eth1.1 up
# udhcpc -i eth1.1
上面的去掉后，可以上ipv4了，不过ipv6依旧不可以上，
ip -6 route显示如下
=====================================================
root@OpenWrt:/etc# ip -6 route
2001:da8:5000:1405::/64 dev eth0  proto kernel  metric 256  expires 2591777sec 
mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev br-lan  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
fe80::/64 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440 hoplimit 0
default via fe80::223:89ff:fe6a:6a32 dev eth0  proto kernel  metric 1024  
expires 1415sec mtu 1500 advmss 1440 hoplimit 64
root@OpenWrt:/etc# 
======================================================
是不是上面“fe80::/64 dev eth0  ”应该是“fe80::/64 dev eth1”啊

该怎么修改呢？

请指教

此时，你在ssh中应该是可以访问IPv6的吧。你试着在ssh中执行p
ing6 www.bupt.edu.cn。
从你的IPv6路由表来看，你没有正确地配置内网接口br-lan。
接口配置信息保存在/etc/config/network，每次开机后启用配置。�
��的交换芯片划分eth1.0作为内网的三个RJ45接口，因此在内网��
�桥中加入eth1.0。相关的配置信息如下，你可以根据实际情况�
��整。
config 'interface' 'lan'
    option 'type' 'bridge'
    option 'ifname' 'eth1.0'
    option 'proto' 'static'
    option 'ipaddr' '192.168.1.1'
    option 'netmask' '255.255.255.0'
    option 'ip6addr' 'fc00:0101:0101::1/64'
    option 'nat' '1'

事实上，你还可以通过ifconfig命令手动配置网络接口。比如
# ifconfig br-lan add fc00:0101:0101::1/64

如果还有不明之处，请参考下载栏目提供的文档。

我的和ligui的情况差不多，ipv4静态，ipv6自动获取+原生，但是
我ipv4都上不了啊

RG100A 刷的1.1固件 、、、
win7下、、、
学校的网络 ipv4只要填上申请的固定ip 子网掩码 网关 
两个dns就能正常上网。。。。如果想上ipv6就只能用电脑，ipb6
全是自动获取（不能接路由器。。所以才想用这个固件）、��
�、

但是我出现了问题。。。。
dns因为只能填写一个所以我只填了一个。。。（不知道下边��
�问题与这个是否有关系）
op的控制台能正常ping通外网，op的软件源也能正常update，，，
但是路由下的子网却不能访问外网。。。这是什么问题？难��
�是ipv4的nat没有成功？是防火墙的设置问题吗？ 我QQ 1650702280
