# Test VPN status endpoint (readLimiter: 100 req/15min)
for i in {1..105}; do
  curl -s -H "Authorization: Bearer YOUR_TOKEN" \
    http://localhost:12345/api/vpn/status \
    -w "%{http_code}\n" -o /dev/null
done

Expected Result: ✅ First 100 requests return 200, requests 101-105 return 429 (Too Many Requests)

# Test VPN connect endpoint (heavyLimiter: 10 req/15min)
for i in {1..12}; do
  curl -s -X POST -H "Authorization: Bearer YOUR_TOKEN" \
    -H "Content-Type: application/json" \
    -d '{}' \
    http://localhost:12345/api/vpn/connect \
