Configuration Verification Checklist

✅ Network Configuration

• All 19 VLANs created
• Subnets match plan (except PHX-SOV-DBIS - verify /24 vs /20)
• DHCP Server enabled on all VLANs
• All VLANs show "UDM Pro" as router

⏳ Settings Verification (Next Steps)

• Network Isolation: Verify "Isolate Network" is UNCHECKED for all VLANs
• Zone Assignment: Verify all VLANs are in "Internal" zone
• Zone Matrix: Verify Internal → Internal = "Allow All"
• Gateway IPs: Verify gateway IPs match plan (e.g., 10.110.0.1 for BESU-VAL)
• DHCP Ranges: Verify DHCP ranges are configured appropriately

⏳ Testing & Utilization

• Inter-VLAN Routing: Test routing between VLANs
• Firewall Rules: Configure inter-VLAN firewall rules
• VM/Container Assignment: Assign VMs/containers to VLANs
• Connectivity Testing: Test connectivity from each VLAN

---

Critical Settings to Verify

1. Network Isolation (CRITICAL)

For each VLAN:

1. Navigate: Settings → Networks → [VLAN Name]
2. Scroll to "Network" section
3. Ensure "Isolate Network" is UNCHECKED
4. Save if changed

Why: Network Isolation blocks inter-VLAN routing. Must be disabled for VLANs to communicate.

2. Zone Matrix (CRITICAL)

1. Navigate: Policy Engine → Zone Matrix
2. Find: Internal → Internal
3. Verify it says "Allow All"
4. If not, click and change to "Allow All"

Why: Zone Matrix controls inter-zone communication. Internal → Internal = Allow All enables inter-VLAN routing.

3. Zone Assignment

For each VLAN:

1. Navigate: Settings → Networks → [VLAN Name]
2. Verify: Zone = "Internal"
3. All VLANs should be in Internal zone

---

Next Steps for VLAN Utilization

Immediate (Today)

1. ✅ Verify Network Isolation

   • Check all 19 VLANs
   • Ensure "Isolate Network" is unchecked

2. ✅ Verify Zone Matrix

   • Policy Engine → Zone Matrix
   • Internal → Internal = Allow All

3. ✅ Verify PHX-SOV-DBIS Subnet

   • Currently shows /24 (10.202.0.0/24)
   • Plan had /20 (10.202.0.0/20)
   • Verify if /24 is intentional or needs update

Short-term (This Week)

1. Test Inter-VLAN Routing

   # From VLAN 11, test routing to other VLANs
   ping 10.110.0.1  # BESU-VAL
   ping 10.111.0.1  # BESU-SEN
   ping 10.120.0.1  # BLOCKSCOUT
   # etc.
   

2. Configure Firewall Rules

   • Management → Service VLANs
   • Service VLANs → Management
   • Sovereign tenant isolation

3. Assign VMs/Containers to VLANs

   • Via Proxmox Web UI or CLI
   • Test connectivity

Long-term (This Month)

1. Migrate Services to VLANs

   • Move VMs/containers to appropriate VLANs
   • Update service configurations

2. Document VLAN Assignments

   • Document which services are on which VLANs
   • Update architecture documentation

3. Monitor and Optimize

   • Monitor inter-VLAN traffic
   • Optimize firewall rules
   • Adjust as needed

VLAN Utilization Guide

Assigning VMs/Containers to VLANs

Via Proxmox Web UI:

1. Go to: Datacenter → [Host] → VMs/Containers → [VM/Container ID]
2. Click: Hardware → Network Device
3. Edit: Bridge = vmbr0, VLAN Tag = [VLAN ID]
4. Save

Via CLI:

# For containers
pct set <CTID> -net0 name=eth0,bridge=vmbr0,tag=<VLAN_ID>

# For VMs
qm set <VMID> --net0 virtio,bridge=vmbr0,tag=<VLAN_ID>

Example VLAN Assignments

Besu Validators:

• VLAN: 110 (BESU-VAL)
• Subnet: 10.110.0.0/24

Besu Sentries:

• VLAN: 111 (BESU-SEN)
• Subnet: 10.111.0.0/24

Besu RPC:

• VLAN: 112 (BESU-RPC)
• Subnet: 10.112.0.0/24

Blockscout:

• VLAN: 120 (BLOCKSCOUT)
• Subnet: 10.120.0.0/24

FireFly:

• VLAN: 141 (FIREFLY)
• Subnet: 10.141.0.0/24

Sovereign Tenants:

• VLANs: 200-203
• Subnets: 10.200.0.0/20, 10.201.0.0/20, 10.202.0.0/24, 10.203.0.0/20

Testing Inter-VLAN Routing

Test 1: Gateway Connectivity

# From VLAN 11, test routing to other VLAN gateways
ping 10.110.0.1  # BESU-VAL
ping 10.111.0.1  # BESU-SEN
ping 10.112.0.1  # BESU-RPC
ping 10.120.0.1  # BLOCKSCOUT
# etc.

Test 2: VM/Container Connectivity

# After assigning VMs/containers to VLANs
# Test connectivity between VLANs
ping <VM_IP_ON_VLAN_110>  # From VLAN 11
ping <VM_IP_ON_VLAN_120>  # From VLAN 11
# etc.

Test 3: Firewall Rules

# Test firewall rules
# Should allow: Management → Service VLANs (SSH, monitoring)
# Should block: Sovereign tenants → Each other
