Waujito/youtubeUnblock ? reverse-engineered prompt

Build me a Linux tool that helps keep YouTube working when normal network filtering breaks it, especially on routers and small home devices. I want it to work with both a regular userspace app and, if needed, a faster kernel based option, so it can run on OpenWRT, Entware, and обычный Linux machines.

Please make the app installable and easy to configure, with clear firewall setup for modern nftables systems and older iptables setups. It should also support IPv6, have a service file for running in the background, and include simple checks so I can tell whether it is working. If there are any special kernel modules or firewall rules needed, set that up in the project and make the instructions easy to follow.

If you need to look up current OpenWRT or nftables docs online, go ahead. I care most about a reliable build that I can compile and use on a router without having to understand all the networking details myself.
