解決辦法：

由於chromecast是直接找8.8.8.8解析，即使局域網f.q了，但直接解析會被DNS污染。you.tu.be投射不了，我們要做的就是把chromecast 的udp 53端口數據全部劫持到本地路由器，由本地解析。這樣就能在局域網智能f.q的情況下觀看you.tu.be了，本人已經試驗成功。
將chromecast所有DNS解析的請求”劫持”到路由器上，從而避免局域網內的主機使用自定義DNS時被污染，

首先路由器要root，能夠用ssh登錄，登陸后

 

vi /etc/firewall.user

或者winscp登陸，直接復制粘貼。

在/etc/firewall.user上增加兩條規則即可：

 

iptables -t nat -A PREROUTING -s 192.168.1.1/24 -p udp --dport 53 -j DNAT --to 192.168.1.1
iptables -t nat -A PREROUTING -s 192.168.1.1/24 -p tcp --dport 53 -j DNAT --to 192.168.1.1

192.168.1.1是路由器IP，親們根據自己的路由器改正。其實只有第一條就足夠了，DNS解析都是UDP。

或 

#暫時不用這個代碼
iptables -I PREROUTING -t nat -p udp -d 8.8.4.4 --dport 53 -j REDIRECT --to-ports 53
iptables -I PREROUTING -t nat -p udp -d 8.8.8.8 --dport 53 -j REDIRECT --to-ports 53

當然前提是有一個openwrt的路由器。並且裝有shad。owsocks智能翻牆。

如果是極路由，在雲平台https://app.hiwifi.com/store.php 搜索安裝iptables，添加以下命令，並啟用iptables

或者WinSCP連接極路由，編輯/etc/rc.common文件start()位置添加以下命令

iptables -t nat -A PREROUTING -s 192.168.199.1/24 -p udp --dport 53 -j DNAT --to 192.168.199.1
iptables -t nat -A PREROUTING -s 192.168.199.1/24 -p tcp --dport 53 -j DNAT --to 192.168.199.1
iptables -I PREROUTING -t nat -p udp -d 8.8.4.4 --dport 53 -j REDIRECT --to-ports 53
iptables -I PREROUTING -t nat -p udp -d 8.8.8.8 --dport 53 -j REDIRECT --to-ports 53
