TUN Mode (Virtual Network Adapter): Full-System Traffic Forwarding
TUN mode creates a virtual network adapter on your device, intercepting and forwarding all traffic at the network (IP) layer. This ensures that all apps and services — even those that don’t support proxy settings — are routed through the VPN.
Advantage → Full system coverage for all traffic.
Limitation → Because it works at the routing level, connections may be less stable under certain devices or network environments.
System Proxy: Consistent Stability
By attaching your system’s HTTP proxy directly to the VPN service, System Proxy offers a more stable and consistent connection.
Advantage → Smooth, reliable, and stable performance.
Limitation → Because some apps and websites do not support proxy mode, they may still be blocked in certain situations.
