What problem does it solve?
This Skill addresses the issue where the FritzBox 7690 silently drops long-lived TCP connections after 60-90 minutes of inactivity, causing VPN tunnels and other persistent connections to fail.
Core Features & Use Cases
- Diagnose Connection Drops: Identifies intermittent VPN disconnects or long-lived connection failures that occur after a period of uptime.
- Root Cause Analysis: Explains the FritzBox NAT timeout mechanism and its interaction with OS-level TCP keepalive settings.
- Implement Fix: Provides a direct, system-wide solution by adjusting TCP keepalive parameters to prevent NAT entries from expiring.
- Use Case: Troubleshoot why your Netbird VPN connection keeps dropping every hour, even though the internet connection itself is stable.
Quick Start
Apply the recommended TCP keepalive settings to prevent NAT timeouts.
