IPv6 Network Configuration: Access External Connections after ISP Switch & Asus Router Setup

Question

Hello As of July 1, my ISP changed my IP to the v6 protocol. Since then, I have lost outside connection to my network. Outside, I connect through the router with UPC. Besides, it has no task. Sometimes some WiFi devices are connected to it, and permanently, with a cable - an Asus router. Asus...

Anonymous · Answer

What model of this router with UPC and how is it all fastened? Added after 1 [minutes]: The vendor left IPv4 and it works. Added after 41 : - at this address you can check if your IPv6 is working at all.

Technicolor TC7200U with a cable for Asus AC66U and then with a cable and WiFi to other devices.
The provider may have left IPv4 but the technical support said that port forwarding does not work anymore because I do not need it ...

Anonymous · Answer

But how and for what purpose? The purpose of such a combination is incomprehensible. There is double NAT there? Added after 2 [minutes]: Draw a diagram of all devices and describe where the cables are connected (LAN, WAN).

neo_plonsk · Answer

I have Technicolor from ISP and it has little functionality and I don't like it. It served me more as a modem, sometimes a WiFi router if it had a better signal. Asus, on the other hand, serves as a print server, for example, has the WoL function or Torrent download to a USB drive. And as a router

Connect the cable directly to Technikolor and give a screenshot from the ipconfig / all command and the test result from the page:

In fact, the provider gives you IPv6 addressing on end devices, and the problem in the current configuration is your Asus settings. Show tabs Status / LAN / WAN in Asus.

Ps. I read German forums and I am not the only one with this problem So maybe an ISP after all?

Anonymous · Answer

The ISP just turned on IPv6 and your Asus router is running on IPv4 which is why you have a problem.

You need to enable IPv6 in Asus and automatic retrieval of the IP address and DNS for the WAN.

Or otherwise - connect the cable from Technikolor to the LAN port instead of WAN in Asus, disable DHCP in it and then the devices will get addresses by Technikolor.

I did, but what next? What address should I enter into the browser? How can I ping computers by IP in the LAN?

Oh, I also found such a setting:

What to choose there? Static or Native?

Added after 13 [minutes]:

Let's say the device has an IP: "fe80 :: 211: 32ff: fe39: cdd0 / 64 Scope: Link". What is it about?

Okay znalazłem odpowiedź na pytanie dotyczące pingu. Jak będę w domu to sprawdzę. Zastanawia mnie tylko jak mogę łączyć się z danym portem w sieci wewnętrznej z zewnątrz.

Ping po IPv6

Spoiler:

ow do I ping IPv6 enabled address using Windows XP or Vista or Windows ME/Server edition?

Only following Windows product support IPv6 via ping.exe command:

=> Windows Vista

Tutorial details
Difficulty Easy (rss)
Root privileges No
Requirements MS-Windows
Estimated completion time 1m
=> Windows Server 2008

=> Windows XP with SP1 or later

=> Windows version 7/8

=> Windows Server 2003 or above
[Warning examples may require IPv6 enabled gear] WARNING! You must have IPv6 tunnel installed or native IPv6 transport from your ISP to use IPv6 over the Internet. You can always use IPv6 inside your LAN/WAN if you have IPv6 enabled networking gear such as routers and other equipments. You need to install the correct protocol (TCP/IPv6) in LAN settings on MS-Windows.
Ping IPv6 using DNS host name on MS-Windows

Open command prompt and type the following command
ping -6 {host.name}
ping -6 ipv6.google.com

OR
ping -6 www.cyberciti.biz

Where ipv6.google.com or www.cyberciti.biz is a name that can be resolved to an IPv6 address through entries in the local hosts file, or through AAAA resource records that are present in your Domain Name System (DNS) infrastructure. When you identify the target host by name rather than IPv6 address, it is necessary to include the -6 parameter.

To ping using an IPv6 address, use the Ping.exe syntax as follows:
ping IPv6Address [%ZoneID]
ping 2001:4860:0:2001::68

2001:4860:0:2001::68 is gloable IPv6 address. To ping to the link-local address fe80::260:97ff:fe02:6ea5 using zone ID 4 (the interface index of an installed Ethernet adapter), use the following command:
ping fe80::260:97ff:fe02:6ea5%4

szwagros · Answer

With IPv6, port forwarding is unnecessary - according to the RIPE guidelines, each end client receives its own subnet of public addresses and each of its devices is visible under the address assigned to it.
http://www.ripe.net/internet-coordination/press-centre/understanding-ip-addressing
Don't be impressed with the address 80.119.78.212 - this is the result of a 6to4 nat to allow access to non-IPv6 hosts. Unfortunately, such nat does not work the other way around.

I understand that every PC will have an external IP. But on one such PC I will have 3-4 services that used to run on separate ports. How will I be able to get to them now? Just : ?

Anonymous · Answer

Those devices that have services exposed to the world connect directly to Technikolor - they will receive a public IPv6 address and will be protected by a firewall. What can not be connected to the modem (or should not be exposed to the outside) should still be attached to Asus.

Exactly, but if you do it, for example, through a browser, it must support IPv6.

neo_plonsk · Answer

I would do as you say but this Technicolor has no WoL and this is my biggest problem.
