NAT64/DNS64安装手册
NAT64采用tayga实现，DNS64采用bind9.8实现。
1平台搭建
平台为ubuntu12.04 Desktop版本。正常安装即可。
2NAT64（tayga）
2.1安装
在终端模式下输入
sudoapt-get install tayga
2.2配置
2.2.1相关设置
Sudo gedit /etc/tayga.conf
按照说明配置，目前实现方案不需要修改。
2.2.2创建、启动设备
tayga–mktun
iplink set nat64 up
2.2.3地址、路由配置
ip addr add192.168.0.1dev nat64(修改为本机IPv4地址)
ip addr add2001:db8:1::1dev nat64 (修改为本机IPv6地址)
ip route add 192.168.255.0/24 dev nat64（不需要修改）
ip route add 2001:db8:1:ffff::/96 dev nat64（不需要修改）
2.2.4启动IPv4、IPv6转发
sysctl -w net.ipv4.conf.all.forwarding=1
sysctl -w net.ipv6.conf.all.forwarding=1
2.2.5启动tayga
tayga
可使用tayga –d进入debug模式。
ping6 2001:db8:1:ffff::192.168.0.1（(修改为本机IPv4地址)）
2.2.6NAT44设置
iptables -t nat -A POSTROUTING -s192.168.255.0/24 -j SNAT --to-source192.168.0.1(修改为本机IPv4地址)
iptables-A FORWARD -s 192.168.255.0/24 -i nat64 -j ACCEPT
3DNS64 bind9
3.1安装
sudo apt-get install bind9
3.2配置
sudo gedit /etc/bind/named.conf.options
修改为如下：
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk.Seehttp://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addressesreplacing
// the all-0's placeholder.
listen-on-v6 { any; };
allow-query { any; };
dns64 2001:db8:1:ffff::/96 {
clients { any; };
};
forwarders {
159.226.8.7;
};
//=================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys.See https://www.isc.org/bind-keys
//================================================================
dnssec-validation auto;
auth-nxdomain no;#conform to RFC1035
listen-on-v6 { any; };
};
修改完成后，输入named.conf查看修改是否成功。
3.3启动bind9
Bind9默认安装后开机启动。设置完成后，输入
/etc/init.d/bindrestart
4使用
4.1Windows
用管理员权限进入cmd，输入
netsh
>interfaceipv6
>add route 2001:db8:1:ffff::/96 "本地连接"2001:db8:1::1（修改为机器的ipv6地址）（为服务器的ipv6地址）
然后设置DNS服务器为NAT64地址即可
4.2Linux
添加路由
ip route add 2001:db8:1:ffff::/96 via2001:db8:1::1（修改为机器的ipv6地址）
然后设置DNS服务器为NAT64地址即可（为服务器的ipv6地址）
服务器地址：192.168.130.42
