I have a question on how or if I can acceive this.
My ISP's router/modem has ipv6 and gets a /64 prefix for connected devices.
That modem is connected to my own router’s wan. So wan get’s an ipv6 from the isp. But since it is a /64 prefix, I can not get ipv6 down to my other interfaces/lan.
Now it seems like the ipv6 given is static. The /64 prefix is displayed on the modem's webpage, so I tried to copy that prefix address and set it as static prefix on my wan interface. The idea is to “clone” the prefix and use it on my lan interface. (What are the odds to randomly get an overlapping address? Lol) As far as I can tell, it does work somewhat. Meaning that my lan interface does pick up the prefix from wan through priority. So in theory, I should be able to have my lan devices receive it. At least the dhcpv6 says it hands out these addresses.
But I run into some other issue, preventing me from properly using the “stolen” v6 subnet. I am not sure what exactly. I have set my router as the dns server (which forwards the requests). My devices pick up their set static address (with suffix). So maybe something is wrong with the shared gateway? On my PC it shows some local fe**:: address. My router is set to use fd**:: addresses, so I assume that it's from the ISP's device.
All I know for sure is that various test sites say I have no ipv6 active.
My lan interface is set to hybrid mode. No master. I previously have tried relay with wan master, but with limited success.
Has anyone some idea what I need to set/change? Or at least what additional info I should post?
Oh no no, the device ip is a public 2001:: address.
The gateway is noted as a local fe:: address, which I assume was given by the ISP’s modem/router, since my router is set to hand out fd:: addresses. So my devices have a 2001:: and a fd:: address, and a fe:: gateway address.
