Could you build this?
No Building kernel-enforced firewalling and DNS filtering modules for OpenWrt embedded devices demands deep Linux kernel networking, Netfilter/eBPF, and C/Lua embedded systems expertise.
What it would actually take: Implemented as a C/C++ or Rust daemon using Netfilter/iptables/nftables hooks or eBPF running on MIPS/ARM OpenWrt architectures alongside a dnsmasq or custom DNS proxy. Key difficulties involve low-memory footprint constraints on home routers, kernel module cross-compilation across diverse target architectures, and maintaining zero network latency degradation. Requires embedded Linux networking engineering skills.
