How to allocate IPv6 to devices connected to a downstream router running OpenWRT?

[HC1337]

nope nothing there either

should the router itself have a DHCPv6 IP? In the stock firmware it didn't work like that, it just passed on the IPv6 addresses from the Jio ONT to the Clients connected to the router.

Is there any way you can show me how to do these throught the LuCI interface? Some screenshots perhaps? I'm not really good at linux to begin with, so this is a bit difficult for me and I'm sure I have been doing something wrong all along.

Using default factory configuration, your A6 should get an IPv6 address, then you can setup ra and dhcpv6 relay.

Ok, after resetting to factory defaults my router is getting a IPv6 address what to do now

Ok, I figured it out turning on RA all the devices are now getting a IPv6 address but what about the addresses starting with fdcd:4dxx:xxxx?

Turning off IPv6 assingment length in LAN interface fixed that aswell.

Thank You very much for the help, really appreciate it.

Well now I am having another problem

I am getting the IPv6 IPs but they aren't reachable and even windows says that IPv6 doesn't have internet connectivity. Any fixes?

Also in IPv6 test (ipv6-test.com) DNS6+IP6 is unreachable

@HC1337 can you give me step by step tutorial on how do enable ipv6 on this router?

@nishantt6969 pass-through not working ?

 

[nishantt6969]

idk whats that and where to find it, I am on openwrt.

@nishantt6969 In interfaces go to WAN6 and set IPv6 to relay mode, do the same to the LAN interface.
