ZIVPN Tunnel (SSH/DNS/UDP) VPN provides tools for setting up and managing VPN tunnels using SSH, DNS or UDP. Its configuration options include a payload generator, custom request headers and a TCP No Delay setting. The app can be used without root access, according to the supplied description.

Tunnel configuration

The payload generator creates custom payload configurations for a connection. For SSH, the app supports a direct connection or a route through an HTTP proxy. Users can also customize request headers. These options allow different parts of the tunnel setup to be configured within the app.

Traffic routing and DNS

Apps filtering and split tunneling let users select which apps or websites use the VPN tunnel and which do not. A custom DNS setting allows a DNS server to be specified. TCP No Delay is another configurable option; the source describes it as a way to reduce delay, but does not provide a particular performance result.

Connection sharing

The app supports sharing an SSH/VPN connection with other devices. Together with its SSH, DNS and UDP tunnel support, these settings cover connection setup, traffic selection and sharing. The supplied description does not specify which DNS providers or proxy configurations are available, so those details may depend on the connection setup.
