VPN Cascading occurs when a VPN connection passes through multiple VPN servers simultaneously. Typically, each VPN can only hide one public IP address at a time, meaning that if a router can only handle one VPN connection, users would need an additional VPN router for every server the data passes through to conceal each server’s public IP address.
With ZBT’s SDK4.1.0 update, VPN Cascading is now supported on ZBT routers. This allows a single ZBT router to host a VPN server while also forwarding data to a VPN client within the same device. In other words, users can set up sophisticated VPN configurations using just one device.
VPN Cascading on ZBT Routers
Why It Matters
With VPN Cascading, users no longer need multiple devices to manage several VPNs simultaneously.
Lower Latency
When data requests are made from the public internet, the requests pass through several layers of devices or servers, each layer increasing the latency as data is processed and routed onward. Reducing the number of devices handling the VPN reduces the physical distance data needs to travel, cutting down overall latency while still processing the VPN encryption.
Simplified Network Management
Reducing the number of devices in an office or home network lowers deployment costs and streamlines device monitoring and maintenance. A single, multitasking device minimizes expenses related to hardware, upkeep, and potential replacement.
Common Use Cases for VPN Cascading
A typical scenario involves users remotely accessing a home or office VPN server and using that server to connect to the public internet. In most corporate network setups, internal resources such as Wi-Fi printers, sensitive files, or local web servers are shielded from the public internet, safeguarding digital assets and maintaining online privacy.
VPN Cascading with ZBT Routers
To securely access internal network resources at home or in the office, the ZBT ZX-Gateway (ZBT-MT2500/ZBT-MT2500A) can host a VPN server and use the VPN Cascading feature to forward its data to the VPN client within the same device. This effectively conceals the public IP addresses of both the remote access device and the office VPN server.
