NATBypass is a Go implementation of the lcx/htran port-forwarding tool that establishes TCP reverse tunnels for NAT traversal. It supports listening, transparent proxying, and slave connection modes to expose internal network services through a public host, bypassing inbound firewall restrictions.
Use cases
- expose an internal RDP service through a public server
- bypass firewall inbound restrictions with a reverse TCP tunnel
- forward traffic between two listening ports
- create a transparent port proxy on a local machine
- penetration testing in NAT network environments
- log forwarded TCP traffic for analysis
When to choose
- you need a lightweight, single-binary lcx-compatible TCP tunnel
- the target host allows outbound connections but blocks inbound ones
- you want a simple Go-based alternative to frp for basic port forwarding
When to avoid
- you need UDP forwarding (not yet supported)
- you need encrypted or authenticated tunnels
- you need a production-grade NAT traversal solution with web UI and configuration files
