    Nipe

    Nipe

    An engine to make Tor network your default gateway

    Nipe is a Perl-based engine whose primary aim is to make the Tor network act as the default gateway for outgoing traffic. In practice, it configures system firewall rules (iptables) and network routing so that almost all IPv4 traffic is redirected through Tor. The tool provides commands such as install, start, stop, restart, and status to manage its behavior. When “start” is issued, it sets up the necessary rules; when “stop” is used, it attempts to remove those rules. Nipe currently...

    File Tunnel

    File Tunnel

    Tunnel TCP connections through a file

    ...This makes it useful in environments where direct TCP connectivity is blocked but a shared folder, FTP server, S3-compatible storage, Dropbox folder, RDP drive share, or similar file channel is available. The project provides portable executables for Windows, Linux, and macOS, which makes it practical for cross-platform testing. Its documentation includes examples for bypassing firewall limitations, tunneling through FTP, using remote internet access, and routing through remote desktop file shares. File-Tunnel is best understood as a specialized connectivity workaround for controlled environments where file access exists but normal network routing does not.

    DSVPN

    A dead simple VPN

    ...No lousy documentation to read. No configuration file. No post-configuration. Run a single-line command on the server, a similar one on the client and you're done. No firewall and routing rules to manually mess with. Doesn't leak between reconnects if the network doesn't change. Blocks IPv6 on the client to prevent IPv6 leaks. Works on Linux (kernel >= 3.17), macOS and OpenBSD, as well as DragonFly BSD, FreeBSD and NetBSD in client and point-to-point modes. Adding support for other operating systems is trivial.
