Core workflow
Everything needed to run and troubleshoot a personal VPN setup.
VPN Lifecycle
Install, start, stop, and observe the iOS Packet Tunnel connection through Apple NetworkExtension.
Connection Monitor
View aggregate proxied traffic, active connection direction, and live connection state for a quick health check.
Built-in Diagnostics
Use tunnel lifecycle logs, sing-box kernel logs, and connectivity probes to find DNS, handshake, timeout, or routing issues.
Precise routing
Rules that match how you actually use the network.
JNet supports multiple routing groups, geosite and geoip rule sets, locked fallback behavior, direct Apple Push traffic, and private network routing controls. Local and private destinations can stay direct by default, while selected private CIDRs can be sent through the proxy when a remote LAN needs it.
- Multiple rule groups for different scenarios
- Catch-all policy for unmatched traffic
- Per-CIDR private network proxy overrides
- DNS, tunnel stack, MTU, IPv6, and strict route settings
Privacy first
Designed to keep VPN configuration and diagnostics under your control.
JNet stores configuration on device and uses the iOS VPN framework to run the tunnel. Diagnostic logs are user-controlled and can be disabled when no output is desired.
