# Network Architecture - Enterprise Orchestration Plan
**Navigation:** [Home](/docs/01-getting-started/README.md) > [Architecture](/docs/01-getting-started/README.md) > Network Architecture
**Last Updated:** 2025-01-20
**Document Version:** 2.0
**Status:** 🟢 Active Documentation
**Project:** Sankofa / Phoenix / PanTel · ChainID 138 · Proxmox + Cloudflare Zero Trust + Dual ISP + 6×/28
---
## Overview
This document defines the complete enterprise-grade network architecture for the Sankofa/Phoenix/PanTel Proxmox deployment, including:
- **Hardware role assignments** (2× ER605, 3× ES216G, 1× ML110, 4× R630)
- **6× /28 public IP blocks** with role-based NAT pools
- **VLAN orchestration** with private subnet allocations
- **Egress segmentation** by role and security plane
- **Cloudflare Zero Trust** integration patterns
---
## Core Principles
1. **No public IPs on Proxmox hosts or LXCs/VMs** (default)
2. **Inbound access = Cloudflare Zero Trust + cloudflared** (primary)
3. **Public IPs used for:**
- ER605 WAN addressing
- **Egress NAT pools** (role-based allowlisting)
- **Break-glass** emergency endpoints only
4. **Segmentation by VLAN/VRF**: consensus vs services vs sovereign tenants vs ops
5. **Deterministic VMID registry** + IPAM that matches
---
## 1. Physical Topology & Hardware Roles
> **Reference:** For complete physical hardware inventory including IP addresses, credentials, and detailed specifications, see **[PHYSICAL_HARDWARE_INVENTORY.md](PHYSICAL_HARDWARE_INVENTORY.md)**.
### 1.1 Hardware Role Assignment
#### Edge / Routing
- **ER605-A (Primary Edge Router)**
- WAN1: Spectrum primary with Block #1
- WAN2: ISP #2 (failover/alternate policy)
- Role: Active edge router, NAT pools, routing
- **ER605-B (Standby Edge Router / Alternate WAN policy)**
- Role: Standby router OR dedicated to WAN2 policies/testing
- Note: ER605 does not support full stateful HA. This is **active/standby operational redundancy**, not automatic session-preserving HA.
#### Switching Fabric
- **ES216G-1**: Core / uplinks / trunks
- **ES216G-2**: Compute rack aggregation
- **ES216G-3**: Mgmt + out-of-band / staging
#### Compute
- **ML110 Gen9**: "Bootstrap & Management" node
- IP: 192.168.11.10
- Role: Proxmox mgmt services, Omada controller, Git, monitoring seed
- **4× Dell R630**: Proxmox compute cluster nodes
- Resources: 512GB RAM each, 2×600GB boot, 6×250GB SSD
- Role: Production workloads, CCIP fleet, sovereign tenants, services
---
## 2. ISP & Public IP Plan (6× /28)

## 3. Layer-2 & VLAN Orchestration Plan
### 3.1 VLAN Set (Authoritative)
> **Migration Note:** Currently on flat LAN 192.168.11.0/24. This plan migrates to VLANs while keeping compatibility.
| VLAN ID | VLAN Name | Purpose | Subnet | Gateway |
|--------:|-----------|---------|--------|---------|
| **11** | MGMT-LAN | Proxmox mgmt, switches mgmt, admin endpoints | 192.168.11.0/24 | 192.168.11.1 |
| 110 | BESU-VAL | Validator-only network (no member access) | 10.110.0.0/24 | 10.110.0.1 |
| 111 | BESU-SEN | Sentry mesh | 10.111.0.0/24 | 10.111.0.1 |
| 112 | BESU-RPC | RPC / gateway tier | 10.112.0.0/24 | 10.112.0.1 |
| 120 | BLOCKSCOUT | Explorer + DB | 10.120.0.0/24 | 10.120.0.1 |
| 121 | CACTI | Interop middleware | 10.121.0.0/24 | 10.121.0.1 |
| 130 | CCIP-OPS | Ops/admin | 10.130.0.0/24 | 10.130.0.1 |
| 132 | CCIP-COMMIT | Commit-role DON | 10.132.0.0/24 | 10.132.0.1 |
| 133 | CCIP-EXEC | Execute-role DON | 10.133.0.0/24 | 10.133.0.1 |
| 134 | CCIP-RMN | Risk management network | 10.134.0.0/24 | 10.134.0.1 |
| 140 | FABRIC | Fabric | 10.140.0.0/24 | 10.140.0.1 |
| 141 | FIREFLY | FireFly | 10.141.0.0/24 | 10.141.0.1 |
| 150 | INDY | Identity | 10.150.0.0/24 | 10.150.0.1 |
| 160 | SANKOFA-SVC | Sankofa/Phoenix/PanTel service layer | 10.160.0.0/22 | 10.160.0.1 |
| 200 | PHX-SOV-SMOM | Sovereign tenant | 10.200.0.0/20 | 10.200.0.1 |
| 201 | PHX-SOV-ICCC | Sovereign tenant | 10.201.0.0/20 | 10.201.0.1 |
| 202 | PHX-SOV-DBIS | Sovereign tenant | 10.202.0.0/20 | 10.202.0.1 |
| 203 | PHX-SOV-AR | Absolute Realms tenant | 10.203.0.0/20 | 10.203.0.1 |
### 3.2 Switching Configuration (ES216G)
- **ES216G-1**: **Core** (all VLAN trunks to ES216G-2/3 + ER605-A)
- **ES216G-2**: **Compute** (trunks to R630s + ML110)
- **ES216G-3**: **Mgmt/OOB** (mgmt access ports, staging, out-of-band)
**All Proxmox uplinks should be 802.1Q trunk ports.**
---
## 4. Routing, NAT, and Egress Segmentation (ER605)
### 4.1 Dual Router Roles
- **ER605-A**: Active edge router (WAN1 = Spectrum primary with Block #1)
- **ER605-B**: Standby router OR dedicated to WAN2 policies/testing (no inbound services)
### 4.2 NAT Policies (Critical)
#### Inbound NAT
- **Default: none**
- Break-glass only (optional):
- Jumpbox/SSH (single port, IP allowlist, Cloudflare Access preferred)
- Proxmox admin should remain **LAN-only**
#### Outbound NAT (Role-based Pools Using /28 Blocks)
| Private Subnet | Role | Egress NAT Pool | Public Block |
|----------------|------|-----------------|--------------|
| 10.132.0.0/24 | CCIP Commit | **Block #2** `<PUBLIC_BLOCK_2>/28` | #2 |
| 10.133.0.0/24 | CCIP Execute | **Block #3** `<PUBLIC_BLOCK_3>/28` | #3 |
| 10.134.0.0/24 | RMN | **Block #4** `<PUBLIC_BLOCK_4>/28` | #4 |
| 10.160.0.0/22 | Sankofa/Phoenix/PanTel | **Block #5** `<PUBLIC_BLOCK_5>/28` | #5 |
| 10.200.0.0/20–10.203.0.0/20 | Sovereign tenants | **Block #6** `<PUBLIC_BLOCK_6>/28` | #6 |
| 192.168.11.0/24 | Mgmt | Block #1 (or none; tightly restricted) | #1 |
This yields **provable separation**, allowlisting, and incident scoping.
---
## 5. Proxmox Cluster Orchestration
### 5.1 Node Layout
- **ml110 (192.168.11.10)**: mgmt + seed services + initial automation runner
- **r630-01..04**: production compute
### 5.2 Proxmox Networking (per host)
- **`vmbr0`**: VLAN-aware bridge
- Native VLAN: 11 (MGMT)
- Tagged VLANs: 110,111,112,120,121,130,132,133,134,140,141,150,160,200–203
- **Proxmox host IP** remains on **VLAN 11** only.
### 5.3 Storage Orchestration (R630)
**Hardware:**
- 2×600GB boot (mirror recommended)
- 6×250GB SSD
**Recommended:**
- **Boot drives**: ZFS mirror or hardware RAID1
- **Data SSDs**: ZFS pool (striped mirrors if you can pair, or RAIDZ1/2 depending on risk tolerance)
- **High-write workloads** (logs/metrics/indexers) on dedicated dataset with quotas
---
## 6. Cloudflare Zero Trust Orchestration
### 6.1 cloudflared Gateway Pattern
Run **2 cloudflared LXCs** for redundancy:
- `cloudflared-1` on ML110
- `cloudflared-2` on an R630
Both run tunnels for:
- Blockscout
- FireFly
- Gitea
- Internal admin dashboards (Grafana) behind Cloudflare Access
**Keep Proxmox UI LAN-only**; if needed, publish via Cloudflare Access with strict posture/MFA.

## 8. Network Security Model
### 8.1 Access Patterns
1. **No Public Access (Tunnel/VPN Only)**
- Besu Validators (VLAN 110)
- Besu Archive/Infrastructure (VLAN 113)
- CCIP Ops/Admin (VLAN 130)
- CCIP Monitoring (VLAN 131)
2. **Cloudflare Tunnel (Primary)**
- Blockscout (VLAN 120) - Emergency VIP: 76.53.10.35
- Besu RPC (VLAN 112) - Emergency VIP: 76.53.10.36
- FireFly (VLAN 141) - Emergency VIP: 76.53.10.37
- Indy (VLAN 150) - Emergency VIP: 76.53.10.39
- Sankofa/Phoenix/PanTel (VLAN 160) - Emergency VIP: 76.53.10.38
3. **Role-Based Egress NAT (Allowlistable)**
- CCIP Commit (VLAN 132) → Block #2
- CCIP Execute (VLAN 133) → Block #3
- RMN (VLAN 134) → Block #4
- Sankofa/Phoenix/PanTel (VLAN 160) → Block #5
- Sovereign tenants (VLAN 200-203) → Block #6
4. **Cloudflare Access / VPN Only**
- CCIP Ops/Admin (VLAN 130)
- CCIP Monitoring (VLAN 131) - Optional dashboard publishing
---
## 9. Implementation Notes
### 9.1 Gateway Configuration
- All private subnets use `.1` as the gateway address
- Example: VLAN 110 uses `10.110.0.1` as gateway
- VLAN 11 (MGMT) uses `192.168.11.1` (legacy compatibility)
### 9.2 Subnet Sizing
- **/24 subnets:** Standard service VLANs (256 addresses)
- **/22 subnet:** Sankofa/Phoenix/PanTel (1024 addresses)
- **/20 subnets:** Phoenix Sovereign Cloud Bands (4096 addresses each)
### 9.3 IP Address Allocation
- **Private IPs:**
- VLAN 11: 192.168.11.0/24 (legacy mgmt)
- All other VLANs: 10.x.0.0/24 or /20 or /22 (VLAN ID maps to second octet)
- **Public IPs:** 6× /28 blocks with role-based NAT pools
- **All public access** should route through Cloudflare Tunnel for security
### 9.4 VLAN Tagging
- All VLANs are tagged on the Proxmox bridge
- Ensure Proxmox bridge is configured for **VLAN-aware mode**
- Physical switch must support VLAN tagging (802.1Q)
---
## 10. Configuration Files
This architecture should be reflected in:
- `config/network.conf` - Network configuration
- `config/proxmox.conf` - VMID ranges
- Proxmox bridge configuration (VLAN-aware mode)
- ER605 router configuration (NAT pools, routing)
- Cloudflare Tunnel configuration
- ES216G switch configuration (VLAN trunks)
