• VyOS routing
• Unbound DNS (DNS over TLS)
• Kea DHCP
• nftables firewall
• Prometheus node exporter

Network Interfaces:

• eth0: WAN (DHCP from Telus)
• eth1: LAN (192.168.100.1/24)
• eth2: Guest (192.168.200.1/24)
• eth3: Management (192.168.1.1/24)

Configuration: router-vm/configuration.nix

AI Agent VM (VM 300)

Purpose: Autonomous network monitoring and management

Services:

• Autonomous monitoring agent (Python)
• Prometheus server (port 9090)
• Grafana dashboards (port 3000)
• Alert manager
• Prometheus node exporter

Network:

• eth0: LAN (192.168.100.20/24)

Configuration: ai-agent-vm/configuration.nix

Installation

1. Install NixOS Base System

Boot VM from NixOS ISO and partition disks:

# Partition disk
parted /dev/sda -- mklabel gpt
parted /dev/sda -- mkpart ESP fat32 1MiB 512MiB
parted /dev/sda -- set 1 esp on
parted /dev/sda -- mkpart primary 512MiB 100%

# Format
mkfs.fat -F 32 -n boot /dev/sda1
mkfs.ext4 -L nixos /dev/sda2

# Mount
mount /dev/disk/by-label/nixos /mnt
mkdir -p /mnt/boot
mount /dev/disk/by-label/boot /mnt/boot

# Generate hardware config
nixos-generate-config --root /mnt

2. Copy Configuration

For Router VM:

# Copy configuration from this repository
scp vm-configs/router-vm/configuration.nix nixos@VM_IP:/tmp/
ssh nixos@VM_IP "sudo cp /tmp/configuration.nix /mnt/etc/nixos/"

For AI Agent VM:

# Copy both configuration and agent script
scp vm-configs/ai-agent-vm/configuration.nix nixos@VM_IP:/tmp/
scp vm-configs/ai-agent-vm/autonomous_agent.py nixos@VM_IP:/tmp/
ssh nixos@VM_IP "sudo cp /tmp/configuration.nix /mnt/etc/nixos/"

3. Install NixOS

# Run installation
nixos-install

# Set root password when prompted

# Reboot
reboot

4. Post-Installation

After first boot:

# SSH into the VM
ssh admin@<VM_IP>

# Update system (if needed)
sudo nixos-rebuild switch

# Check services
systemctl status bird2         # Router VM only
systemctl status orion-agent   # AI Agent VM only
systemctl status prometheus    # AI Agent VM only
systemctl status grafana       # AI Agent VM only

Configuration Management

Updating Configurations

Configurations are declarative - edit the .nix files and rebuild:

# Edit configuration
vim /etc/nixos/configuration.nix

# Test configuration (don't activate)
sudo nixos-rebuild test

# Apply configuration
sudo nixos-rebuild switch

# Rollback if needed
sudo nixos-rebuild --rollback

Version Control

Keep configurations in Git:

# After making changes
cd /path/to/luci-macOSX-PROXMOX
git add vm-configs/
git commit -m "Update VM configurations"
git push

Customization

Router VM

Add BGP peer: Edit router-vm/configuration.nix:

protocol bgp new_peer {
  local as 394955;
  neighbor <IP> as <ASN>;

  ipv4 {
    import all;
    export where source = RTS_STATIC;
  };
}

Add firewall rule:

# In nftables.ruleset
iif eth1 tcp dport <PORT> accept

Change network ranges:

networking.interfaces.eth1.ipv4.addresses = [{
  address = "192.168.X.1";
  prefixLength = 24;
}];

AI Agent VM

Adjust monitoring interval: Edit ai-agent-vm/autonomous_agent.py:

self.check_interval = 60  # seconds

Add monitoring targets: Edit ai-agent-vm/configuration.nix:

services.prometheus.scrapeConfigs = [
  {
    job_name = "new-target";
    static_configs = [{
      targets = [ "IP:PORT" ];
    }];
  }
];

Change Grafana password:

services.grafana.settings.security.admin_password = "NEW_PASSWORD";

Troubleshooting

Router VM

BGP not working:

# Check BIRD status
birdc show protocols

# Check BIRD logs
journalctl -u bird2 -f

# Reload BIRD config
birdc configure

Firewall blocking traffic:

# View rules
nft list ruleset

# Check counters
nft list ruleset -a

# Temporarily disable (for testing only!)
systemctl stop nftables

AI Agent VM

Agent not collecting metrics:

# Check agent logs
journalctl -u orion-agent -f

# Check if Prometheus is scraping
curl http://localhost:9090/api/v1/targets

# Manually test router connectivity
curl http://192.168.100.1:9100/metrics

Grafana not accessible:

# Check Grafana status
systemctl status grafana

# Check firewall
nft list ruleset | grep 3000

# View Grafana logs
journalctl -u grafana -f

Security Notes

1. SSH Keys: Add your public keys to configuration:

   users.users.admin.openssh.authorizedKeys.keys = [
     "ssh-rsa AAAAB3... your-key-here"
   ];
   

2. Firewall: Default deny policy - only explicitly allowed traffic passes

3. Updates: Automatic weekly updates enabled:

   system.autoUpgrade.enable = true;
   

4. Change Default Passwords:

   • Grafana: admin / orion2025 → Change immediately!
   • SSH: Disable password auth, use keys only

Support

For issues or questions:

1. Check the main documentation: ../ORION_HYBRID_ARCHITECTURE.md
2. Review NixOS manual: https://nixos.org/manual/nixos/stable/
3. Check service logs: journalctl -u <service> -f
