## Network Zones
|
|
|
|
### Management Zone
|
|
- **Purpose**: Ansible control and infrastructure management
|
|
- **CIDR**: 192.168.1.0/24 (example - adjust per environment)
|
|
- **Access**: Restricted to operations team
|
|
- **Protocols**: SSH (22), HTTPS (443)
|
|
|
|
### Hypervisor Zone
|
|
- **Purpose**: KVM/libvirt hypervisor hosts
|
|
- **Access**: Ansible control node via SSH
|
|
- **Services**: libvirt (16509), SSH (22)
|
|
|
|
### Guest VM Zone
|
|
- **Purpose**: Application and service VMs
|
|
- **Networks**: Multiple virtual networks per purpose
|
|
- Production: 10.0.1.0/24
|
|
- Staging: 10.0.2.0/24
|
|
- Development: 10.0.3.0/24
|
|
|
|
## Virtual Networking (libvirt)
|
|
|
|
### Default NAT Network
|
|
- **Network**: `default`
|
|
- **Type**: NAT
|
|
- **Subnet**: 192.168.122.0/24
|
|
- **DHCP**: Enabled
|
|
- **Use Case**: Development and testing VMs
|
|
|
|
### Bridged Network
|
|
- **Network**: `br0`
|
|
- **Type**: Bridge
|
|
- **Configuration**: Attached to physical NIC
|
|
- **Use Case**: Production VMs requiring direct network access
|
|
|
|
## Firewall Rules
|
|
|
|
### Hypervisor Firewall (firewalld/UFW)
|
|
|
|
**Allowed Inbound**:
|
|
- SSH from Ansible control node (port 22)
|
|
- libvirt management from control node (port 16509)
|
|
|
|
**Denied**:
|
|
- All other inbound traffic (default deny)
|
|
|
|
### Guest VM Firewall
|
|
|
|
**Allowed Inbound**:
|
|
- SSH from hypervisor/management network (port 22)
|
|
- Application-specific ports (per VM purpose)
|
|
|
|
**Allowed Outbound**:
|
|
- HTTPS for package repositories (port 443)
|
|
- DNS queries (port 53)
|
|
- NTP time sync (port 123)
|
|
|
|
## DNS Configuration
|
|
|
|
- **Primary**: 8.8.8.8 (Google DNS)
|
|
- **Secondary**: 1.1.1.1 (Cloudflare DNS)
|
|
- **Future**: Internal DNS server for local name resolution
