    SMTP Tunnel Proxy

    SMTP Tunnel Proxy

    A high-speed covert tunnel that disguises TCP traffic as SMTP email

    SMTP Tunnel Proxy is a high-speed covert tunneling proxy that disguises regular TCP traffic as legitimate SMTP email communication to evade deep packet inspection (DPI) firewalls and censorship systems. It implements a SOCKS5 proxy interface on the client that wraps outbound traffic into an SMTP-like handshake (EHLO, STARTTLS, AUTH) and encrypted payload, making the session appear to DPI systems as a normal email exchange.

    frp

    frp

    A Fast Reverse Proxy

    frp stands for exactly what it is: a fast reverse proxy. It helps you expose a local server behind a NAT or firewall to the Internet. It is currently under development, but already supports TCP and UDP, as well as HTTP and HTTPS protocols where requests can be forwarded to internal services by domain name. It also has a P2P connect mode and many other nifty features. These include configuration files, environment variables, a dashboard that shows you frp's status and proxies' statistics information, an Admin UI that helps you check and manage frpc's configuration, and many others.

    mieru

    mieru

    mieru is a socks5 / HTTP / HTTPS proxy to bypass censorship

    mieru is a secure proxy software suite built around a client called mieru and a server called mita. It is designed to provide SOCKS5, HTTP, and HTTPS proxy access over TCP or UDP-based transport. The project emphasizes traffic that is difficult to classify or probe, making it relevant for privacy-focused and censorship-resistance research. It includes encrypted communication and uses a dedicated protocol rather than simply wrapping a common proxy format. mieru can run on multiple platforms and provides release packages for different operating systems and architectures. ...

    Fabio

    Consul Load-Balancing made simple

    Fabio is an HTTP and TCP reverse proxy that configures itself with data from Consul. Traditional load balancers and reverse proxies need to be configured with a config file. The configuration contains the hostnames and paths the proxy is forwarding to upstream services. This process can be automated with tools like consul-template that generate config files and trigger a reload.

    An advanced, yet simple, tunneling/pivoting tool

    Ligolo-ng is a simple, lightweight and fast tool that allows pentesters to establish tunnels from a reverse TCP/TLS connection using a tun interface (without the need of SOCKS). When running the relay/proxy server, a tun interface is used, packets sent to this interface are translated and then transmitted to the agent's remote network. You need to download the Wintun driver (used by WireGuard) and place the wintun.dll in the same folder as Ligolo.
