macOS Network Tools & AI Remote Access

A collection of scripts and configurations to maintain a clean network environment on macOS and enable secure remote access to local AI services.

🛠 Features

• Network Fixer: An AppleScript tool to flush routing tables, clear DNS caches, and terminate ghost VPN processes (NordVPN, Surfshark, etc.).
• Remote Ollama Gateway: Configuration guide to expose Ollama to a private Tailscale network, bypassing the default localhost restriction.
• DNS Auto-Restoration: Logic to restore local DNS (FRITZ!Box) to ensure ad-blocking remains active after VPN sessions.

🚀 Getting Started

1. Network Repair Tool

To use the repair script, save the following logic as an .app via the macOS Script Editor:

-- Force quit stuck VPN daemons
do shell script "sudo killall -9 NordVPN 'NordVPN Helix' Surfshark Tunnelblick" with administrator privileges

-- Reset routing and DNS
do shell script "sudo route -n flush" with administrator privileges
do shell script "networksetup -setdnsservers Wi-Fi Empty" with administrator privileges

2. Exposing Ollama to Tailscale

To access your Mac's LLMs from a remote VPS:

1. Set the Host Variable:

   launchctl setenv OLLAMA_HOST "0.0.0.0"

2. Restart Ollama and verify the binding:

   netstat -an | grep 11434

Target output: *.11434 or 0.0.0.0.11434

📝 Background

This project was born out of the necessity to manage a complex hybrid network stack (Work VPNs vs. Private Meshnets) without losing access to local infrastructure and AI services.
