Port 3000 Firewall Rule Removal

🎯 Fix Summary

Action: Removed port 3000 firewall rule and added missing ports to ensure complete firewall configuration

Date: March 4, 2026

Reason: AITBC doesn't use port 3000, and firewall rules should only include actually used ports

---

✅ Changes Made

Firewall Configuration Updated

aitbc.md - Main deployment guide:

```bash
# Configure firewall
sudo ufw allow 8000/tcp
sudo ufw allow 8001/tcp
sudo ufw allow 8002/tcp
sudo ufw allow 8006/tcp
sudo ufw allow 9080/tcp
- sudo ufw allow 3000/tcp
+ sudo ufw allow 8009/tcp
+ sudo ufw allow 8080/tcp

# Secure sensitive files

📊 Firewall Rules Changes

Before Fix

# Incomplete firewall rules
sudo ufw allow 8000/tcp  # Coordinator API
sudo ufw allow 8001/tcp  # Exchange API
sudo ufw allow 8002/tcp  # Multimodal GPU
sudo ufw allow 8006/tcp  # Marketplace Enhanced
sudo ufw allow 9080/tcp  # Blockchain RPC
sudo ufw allow 3000/tcp  # ❌ Not used by AITBC
# Missing: 8009, 8080

After Fix

# Complete and accurate firewall rules
sudo ufw allow 8000/tcp  # Coordinator API
sudo ufw allow 8001/tcp  # Exchange API
sudo ufw allow 8002/tcp  # Multimodal GPU
sudo ufw allow 8006/tcp  # Marketplace Enhanced
sudo ufw allow 8009/tcp  # Web UI
sudo ufw allow 9080/tcp  # Blockchain RPC
sudo ufw allow 8080/tcp  # Blockchain Node
# ✅ All AITBC ports included, no unused ports
