Shadowsocks WS 2022 tunneling is a method of transporting arbitrary networking data over an encrypted Shadowsocks WS 2022 connection. It can be used to add encryption to legacy applications. It can also be used to implement VPNs (Virtual Private Networks) and access intranet services across firewalls.

The Shadowsocks WS 2022 connection is used by the application to connect to the application server. With tunneling enabled, the application contacts to a port on the local host that the Shadowsocks WS 2022 client listens on. The Shadowsocks WS 2022 client then forwards the application over its encrypted tunnel to the server. The server then connects to the actual application server - usually on the same machine or in the same data center as the Shadowsocks WS 2022 server. The application communication is thus secured, without having to modify the application or end user workflows.
