上个月家里宽带升级了200M, 顺带看到可以免费享受一路4K的IPTV.

其实一直都知道电信的宽带可以免费申请IPTV, 但是一直都没弄, 主要原因是一直都没找到合适的办法去只用一根网线来解决我上网出口跟IPTV的问题..曾经看到一些方案但是都觉得不合适或者说不够理想, 而在几周前,在Chiphell毒坛看到了一个近乎完美的解决方案https://www.chiphell.com/thread-1421026-1-1.html, 这样一来4K的IPTV自然就可以顺理成章的入住了.

telnet或ssh连接到梅林固件的路由器

Merlin固件访问桥接光猫的脚本

桥接的光猫 192.168.1.1 的设备

 编辑如下两个文件，可以路由直接访问桥接猫
vi nat-start
添加并保存：iptables -t nat -I POSTROUTING -o `nvram get wan0_ifname` -j MASQUERADE

按esc后，输入：wq  保存并退出

 It took me a bit to get this going so i thought i would share. When you are done you will have IPv6 in your home for all your devices.

High level instructions
1. sign up for a (free!) tunnel account @ http://tunnelbroker.net/
2. change your DDNS settings in asuswrt to reset your v4 IP if it changes
3. Setup a ipv6 6in4 tunnel
4. put an ip6tables firewall script on
5. run the test @ http://test-ipv6.com/ and enjoy!

OK, some details.
I assume you can all do #1 without trouble.

For #2, On your asuswrt interface, go to WAN/DDNS. Select the 'www.tunnelbroker.net' provider. In the 'Host Name' put the tunnel ID your tunnel has. This is a ~5 digit number, and appears on your 'Tunnel Details' page on the tunnelbroker.net website after you have logged in. In the "User Name or Email Address" put your user-id which is a really long alphanumeric string for User ID that you will see if you click on "Main Page" (just above account info) on the tunnelbroker.net site. Then enter your password. Once this is done, the DDNS client on the router will update HE each time your IP changes.

For #3, select 'IPV6' on the asuswrt interface. Select 'Tunnel 6in4' for connection type. Enter the Server IPv4 Address from your HE tunnel details page. Enter the Client IPv6 address (without the mask... this should end in ::2). Select 64 for ipv6 prefix len. Select 1480 for Tunnel MTU. Select 255 for Tunnel TTL. In the IPv6 lan settings, take the value from the 'Routed /64' on your tunnel details page, and enter it as LAN ipv6 prefix. Do not put the mask, but end in :: (e.g. X:X:X:X:. Enter 64 for the prefix len. In the IPv6 DNS resolvers, put 2001:470:20::2, 2001:4860:4860::8888, and 2001:4860:4860::8844. Now select 'Enable Router Advertisement'.

@ this stage you should have ipv6 connectivity, you can check that here: http://test-ipv6.com/, or run 'ifconfig' on your linux machine, or ipconfig on your windows machine. These should have gotten an ipv6 from the router via router advertisement. If not, debug until you do.

For #4, you are going to want to do some firewalling I think (If you are happy with all your interior machines open on the internet, skip). Go to the administration/System tab, enable JFFS. Now create a file called /jffs/scripts/firewall-start [i did this via SSH] based on the attachment to this thread. You need to change the top 3 lines to match your tunnel IP interfaces.

This will allow any machine inside your house to do what it wants, but disallows incoming connectivity.

At this stage, re-run the ipv6 test http://test-ipv6.com/, and you should be good to go.

You may wish to remove the bottom 3 lines of the script (the LOG) ones, they are for debugging, but cost a lot of perf.

Some automotive devices use Media Transfer Protocol (MTP) for connecting to your computer. MTP provides a more secure environment for the important system files on your device.

MTP connectivity requires the following.

Windows XP with service pack 3 or later.
Windows Media Player 11 or later.
