    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.

    OpenFortiVPN

    Client for PPP+TLS VPN tunnel services

    openfortivpn is a command-line SSL VPN client for connecting to Fortinet FortiGate gateways without relying on proprietary GUIs. It negotiates the SSL/TLS tunnel, authenticates with credentials (and commonly with two-factor methods), then brings up a secure point-to-point interface and installs routes and DNS settings. The tool aims to be minimal and dependable: a single binary with an INI-style config file, systemd compatibility, and clear runtime diagnostics. It handles details like MTU tuning, split tunneling via pushed routes, and reconnect logic to keep the session stable. ...

    http-proxy-tunnel

    Create nested tunnels through HTTP proxies

    Http-proxy-tunnel creates TCP tunnels through http proxies that permit the CONNECT method. It differs from other proxy tunnelling programs in that it can tunnel through multiple proxies, and can use SSL tunnels. These abilities mean that in combination with a web server that can proxy (such as Apache) you can serve normal web pages from ports 80 and 443 and connect to the server (using ssh say) via those ports at the same time.
