WNDR4700 ip6 wan not working

For Developers
1

I have eth1 (USB RNDIS 4G-LTE 50Mbps Modem) connected to WNDR4700. When I connet this eth1 with my pc directly it provide me ipv4 and ipv6 address.

[ eth1==>WNDR4700==>MANY-PC ]

My question is:

  1. Is my eth1 has assigned any ipv6 address for my WNR4700.
  2. If WNDR4700 is assigning to its client.
  3. The good thing about eth1 is it provide global unique ipv6 address to its client.

2

Help to setup ipv4/ivp6 environment seamlessly, or "dont break your head on ipv6 exiting configuration is good as long it work", any help??? If you need more information, let me know.

the defaults work for most people ok, if the upstream (ISP, modem, whatever) provides full IPv6 support. You have apparently created a new wan interface, so you will likely need to adjust some settings accordingly.

You should show the /etc/config/network and /etc/config/dhcp instead of the screenshot. Also the current address status from "ifconfig" output should tell you if there ip a routable ipv6 address for the router.

https://lede-project.org/docs/user-guide/basic-ipv6-configuration

Ps. It is possible that your modem does not allow for prefix delegation, so an individual PC may get a working address, but router wants a full /64 prefix and does not get it. If that is the case, you may need to set the ipv6 config for relaying as explained in the wiki .

I have altered ifconfig result for hiding MAC, because i am copying other people. I dont know that I should share my MAC on public or not.

Reading https://lede-project.org/docs/user-guide/basic-ipv6-configuration

Looks like you disabling the ipv6 address by dhcpv6, as you have "auto 0" there (so that the interface stays down). You should remove that auto 0 setting or manually do "ifup RNDIS6" to bring the interface up.

The reqaddress and reqprefix are usually unnecessary.

ok,

this is direct connection with PC [ eth1 ==> PC1 ], this is just for information

I am living in India with more than 1.38 billion people, they all are getting smartphone, So I want to tune up with ipv6.

9

this is wrong, there is another layer that is
[ Modem{wan=>eth1}==>WNDR4700{wan+wan6 ==> lan+wifi}==>MANY-PC ]

10

Is there anyway to test my ipv4/ ipv6 connectivity for my application {android, chrome, firefox, ubuntu, windows xp and 10}

11

What is this do I have tweak this, or its ok, don't touch it.
