IPV6 over LAN to WAN cascade?
My ISP is Satan. They gave me a custom made router (manufactured somewhere in China, I have no idea what brand it is, its a white box with my ISP logo on it) - it has only one lan output and I have almost 0 control on the router settings, only DHCP, port forwarding, thats it and I can't connect a regular router because the connection is fiber optic directly and it doesn't work with any other router only their own. I connected to it a TL-WR840N v4 router LAN to WAN. The internet works through IPV4 but I can't get it to work on IPV6. My first router(192.168.1.1) is connecting to my ISP through PPPoE and my second router (192.168.2.1) connects to my first one with the Dynamic IP settings(IPV4). The only setting that gives me an address for IPV6 is Dynamic IPV6 with SLAAC. My PC gets all the addresses IPV4 and IPV6 but I only have internet access on the IPV4. Could someone please help me to figure out if its possible to fix this? Before the cascade I had IPV6 and I don't want to go back to my first router because its a spawn of hell and I hate it. Is it possible to make IPV6 work somehow? Maybe IPV6 static options? Any help is greatly appreciated!
