## What it is
Subnet is a simple, auditable VPN server and client written in Go, using TLS mutual authentication and TUN interfaces to route traffic. It supports traditional full-tunnel VPN setups and exposing remote LANs, though the author recommends WireGuard for real deployments.

## Use cases
- set up a simple self-hosted vpn server
- tunnel all non-lan traffic through another machine
- route traffic through a remote box with nat
- make a remote lan accessible from my machine
- vpn with tls mutual certificate authentication
- lightweight go vpn client and server

## When to choose
- you want a small, readable, auditable VPN codebase in Go
- you need certificate-based mutual TLS authentication for VPN clients
- you want to expose a remote LAN to your machine
- throughput needs are modest (under ~100Mbps)

## When to avoid
- you need high performance or production-grade security - use WireGuard instead
- you need Windows client support
- you want an actively developed project with recent releases
