Could you build this?
No OpenGFW is an autonomous, high-performance deep packet inspection (DPI) and firewall implementation capable of wire-speed filtering, requiring specialized networking and protocol engineering.
What it would actually take: Building a DPI firewall requires deep knowledge of low-level Linux networking (e.g., eBPF/XDP, NFQueue, AF_PACKET, DPDK) and advanced protocol reassembly algorithms in Go, C, or Rust. It involves parsing encrypted SNI, TLS fingerprints (JA3/JA4), DNS queries, and flow reassembly under high concurrency and packet rates without dropping packets.
