Appendix K: OpenGear Configuration
DOCUMENT CATEGORY: Reference
SCOPE: OpenGear console server configuration
PURPOSE: OOB management, Lighthouse enrollment, and serial port configuration
MASTER REFERENCE: OpenGear Documentation
Status: Active
Overview
This appendix provides OpenGear OM1208-8E-L console server configuration templates for Azure Local deployments. These configurations establish secure out-of-band (OOB) management access to infrastructure devices (switches, firewalls, iDRACs) via Lighthouse remote management.
Key Design Elements:
- NET1: Internet-routable uplink for Lighthouse enrollment (DHCP or static)
- NET2 + br0 bridge: OOB management network (192.168.100.0/24, isolated from production)
- 8-port integrated switch: Untagged access to iDRACs and infrastructure devices
- Lighthouse enrollment: Centralized management and secure remote access
- Security hardening: Password policies, brute force protection, firewall zones
Required Firewall Ports for Lighthouse Connectivity
Critical
These ports must be allowed outbound from OpenGear NET1 interface to the Internet for Lighthouse connectivity.
| Protocol | Port | Direction | Purpose | Required |
|---|---|---|---|---|
| TCP | 443 | Outbound | HTTPS - Lighthouse management communication | ✅ YES |
| UDP | 1194 | Outbound | OpenVPN - Lighthouse VPN tunnel | ✅ YES |
| UDP | 51820 | Outbound | WireGuard - Smart Management Fabric (SMF) | ✅ YES |
| UDP | 500 | Outbound | ISAKMP - IPsec (optional) | ⚠️ If using IPsec |
| UDP | 4500 | Outbound | NAT-T - IPsec NAT Traversal (optional) | ⚠️ If using IPsec |
Firewall Configuration Requirements:
- On-Premises Firewall (if present): Must allow the above ports outbound from OpenGear NET1 subnet to Internet
- OpenGear Internal Firewall: Configured in this document (Section 7)
- FortiGate/Edge Firewall: Must allow OpenGear management traffic (see Appendix J: Fortinet Configuration)
Lighthouse FQDN: lighthouse.opengear.com (resolve to public IP, subject to change)
Azure Site-to-Site VPN Routing Considerations
When FortiGate establishes Azure Site-to-Site VPN with BGP routing:
✅ DO
- Allow Azure Jump Host to reach OpenGear OOB management interfaces (br0: 192.168.100.5)
- Advertise OOB subnet (192.168.100.0/24) via BGP to Azure
- Enable routing from Azure VNet to OpenGear for remote management post-VPN
❌ DO NOT
- Route Lighthouse traffic (NET1) through Azure VPN - must remain internet-bound
- Configure default route on NET2/br0 - keeps OOB network isolated
- Block UDP 1194, 51820, or TCP 443 outbound from NET1
Routing Priority
- Lighthouse traffic → NET1 → Internet (via Fabric01 or local internet uplink)
- Azure management traffic → br0 → FortiGate → Azure VPN → Azure Jump Host
- OOB device traffic → br0 (stays local, no routing)

| Device/Port | IP Address | Notes |
|---|---|---|
| OpenGear OM1208 (br0) | 192.168.100.5/24 | OOB management IP |
| Firewall A OOB | 192.168.100.6/24 | Connected to sw0p5 |
| Firewall B OOB | 192.168.100.7/24 | Connected to sw0p6 |
| Switch TOR1 OOB | 192.168.100.8/24 | Connected to sw0p7 |
| Switch TOR2 OOB | 192.168.100.9/24 | Connected to sw0p8 |
| Node 1 iDRAC | 192.168.100.11/24 | Connected to sw0p1 |
| Node 2 iDRAC | 192.168.100.12/24 | Connected to sw0p2 |
| Node 3 iDRAC | 192.168.100.13/24 | Connected to sw0p3 (if 3-node) |
| Node 4 iDRAC | 192.168.100.14/24 | Connected to sw0p4 (if 4-node) |
note
All OOB devices should have:
- IP address in 192.168.100.0/24 subnet
- Subnet mask: 255.255.255.0
- No default gateway configured (keeps OOB isolated)
Configuration Verification
After applying configuration, verify the following:
Network Connectivity
# Verify NET1 has Internet connectivity
ping -c 4 1.1.1.1
# Verify br0 is up and has correct IP
ip addr show br0
# Test OOB device connectivity
ping 192.168.100.11 # iDRAC1
ping 192.168.100.8 # Switch TOR1
Lighthouse Enrollment
# Check Lighthouse connection status
ogcli show system.lighthouse.status
# Expected output: status=online, enrolled=true
Serial Port Status
# List all serial ports and their configuration
ogcli show services.serial_ports
# Verify port labels are correct
ogcli show services.serial_ports.port1.label
Security Configuration
# Verify root is disabled
ogcli show system.users.root.ssh.enabled
ogcli show system.users.root.webui.enabled
# Verify password policy
ogcli show system.security.password_policy
# Verify brute force protection
ogcli show system.security.brute_force

.tar.gzfile - Device will restore and reboot
Troubleshooting
Cannot reach OOB devices from OpenGear
# Verify br0 bridge is up
ip addr show br0
# Verify NET2 is member of br0

# Verify switch ports are in bridge
brctl show br0
# Ping test
ping 192.168.100.11
Lighthouse enrollment failed
# Verify NET1 has Internet connectivity
ping 1.1.1.1
# Check Lighthouse URL is correct
ogcli show system.lighthouse.server_url
# Verify enrollment token is valid
ogcli show system.lighthouse.enrollment_token
# Check firewall allows HTTPS outbound
# Re-enroll
ogcli apply system.lighthouse
Cannot SSH to OpenGear
# Verify SSH service is enabled
ogcli show system.services.ssh.enabled
# Check firewall zones
ogcli show system.firewall.zones
# Verify user has SSH access
ogcli show system.users.<username>.ssh.enabled
Configuration Management Best Practices
- Version Control: Store all site configurations in Git repository
- Naming Convention: Use consistent naming:
opengear-config-<SITE_CODE>-<DATE>.sh - Credentials: Never store passwords in configuration files - use Azure Key Vault
- Backup Schedule: Export configuration after every change
- Testing: Test configurations in lab before production deployment
- Documentation: Document all site-specific deviations from standard template
