Hello gentlemen,
I'm having trouble configuring IPv6 on my Archer C7-v2.
When I do DHCPv6 to my ISP, it returns me with a Global IPv6 address (without IPV6-PD) which, when pinging via LuCi or via SSH, it returns me 0% loss, but when pinging my machine it returns me 100% loss.
@lleachii, I apologize for the lack of clarity.
I am trying to configure internet access via IPv6.
My problem is this: I have IPv6 access only on the LuCi interface when I give a ping6 command on the diagnostics tab, that is via SSH OpenWrt also I can ping6 openwrt.org for example, but on my OS I can't ping6 command for no website IPv6.
I configured raute6 for wan, believing that it would be possible to go to the internet with IPv6 in this way
Atualmente, conforme as imagens de tela, essa é minha configuração, a qual não tenho acesso para internet com IPv6
My ISP may not work with DHCPv6 or else I am doing something very wrong to configure IPv6 on openWrt?
The thing is... there's nothing wrong with your config. If yor ISP doesn't issue a PD, you'll have to install something like NAT for IPv6 for your LAN to use it.
EDIT: and to be clear, the route is incorrect for at least 3 reasons:
it would be your ISP that needs to make routes
you listed a subnet as a gateway, that's invalid anyway
You should not (need to) declare a manual IPv6 default route, remove that route entry again.
Make sure your WAN6 interface is configured to request a prefix ("Request IPv6-address: try", "Request IPv6-prefix of length: Automatic") and make sure that your LAN interface has the "IPv6 assignment length" set to something >= 64.
@lleachii, thanks for the advice. Regarding what you said, I think it is more likely that my ISP will not release IPV6-PD, and in this case I will have to configure a NAT IPv6 (I need to read a little about this because NAT IPv6 I don't know how it does).
@eduperez, thanks for the answer!
Yes exactly, I would like to use this IPv6 from WAN6, which is why I can ping6 on LuCi and SSH
@jow, thanks for the answer!
I've already configured it this way, and even then I don't receive an IPv6-PD... Here are screenshots:
Sorry if I am being obtuse, and sorry again if I am hijacking someone's else thread... but I just do not get the issue with the /64 network and the need for NAT6, perhaps I am not as well informed about IPv6 as I though.
If the ISP issued a /64 (as many ISP's do) to the OP, isn't OP supposed to just use that address, so all devices in his LAN get an address within that /64 subnet? Why the need for NAT6, then?
Also, should't OP's LAN interface have an address in the 2804:.../64 range (it doesn't)? Shouldn't all his devices connected to LAN have an address in the 2804:.../64 range (not tested)? Or I am missing something here?
Just like if you're issued a WAN IPv4 address from a /24 range - it doesn't mean that the remaining 251 IPs in the subnet are available for your usage.
Honestly, just get a tunnel, or pretend you don't have IPv6, since you actually basically don't. Getting one IPv6 assigned to you is like going to a restaurant and getting one grain of rice... Technically maybe you were served... but you didn't actually get a meal.
But I'd call the ISP, they probably just haven't got a clue but they might just need to enable something so you get a prefix designated.
Thank you very much for the tips and advice of all. @dlakelan, I will contact my ISP and request a correction, a light or a correct IPv6-PD release; I'll do it tomorrow and i will keep this topic up to date.
