π Protocol Guide
TProxy-TCP-UDP
TProxy makes "system-wide proxy" practical. Rather than asking each app to point at a proxy, it sits in the kernel and silently diverts TCP and UDP connections toward the proxy engine, preserving the true destination address for correct routing decisions.
Why TProxy Is Useful
- Zero app changes: Existing software needs no proxy awareness.
- TCP and UDP together: Both traffic types pass through the same mechanism.
- Fast by design: Kernel-level processing keeps overhead small.
- Linux-based: Native to the netfilter architecture.
- Smart filtering: Decisions can follow IPs, ports, and more.
