Configuration from .env

PROXMOX_HOST=192.168.11.10          # ml110-01
PROXMOX_PORT=8006
PROXMOX_USER=root@pam

PROXMOX_TOKEN_VALUE=***             # Configured ✅

Tunnel Configurations

Tunnel Infrastructure

• Container: VMID 102
• Host: 192.168.11.12 (r630-02)
• Network: 192.168.11.0/24 (can access all Proxmox hosts)

Active Tunnels

#	Tunnel Name	Tunnel ID	Public URL	Internal Target	Metrics Port
1	tunnel-ml110	ccd7150a-9881-4b8c-a105-9b4ead6e69a2	ml110-01.d-bis.org	192.168.11.10:8006	9091
2	tunnel-r630-01	4481af8f-b24c-4cd3-bdd5-f562f4c97df4	r630-01.d-bis.org	192.168.11.11:8006	9092
3	tunnel-r630-02	0876f12b-64d7-4927-9ab3-94cb6cf48af9	r630-02.d-bis.org	192.168.11.12:8006	9093

Conflicts Identified

✅ No Port Conflicts

• Each tunnel uses different metrics ports (9091, 9092, 9093)
• All tunnels correctly target port 8006 on different hosts
• No overlapping port usage

⚠️ Network Segmentation Conflict

• Issue: Your machine (192.168.1.0/24) cannot reach Proxmox network (192.168.11.0/24)
• Impact: Direct API access blocked
• Status: Expected behavior - different network segments

✅ Tunnel Configuration Correct

• All tunnels properly configured
• DNS records point to tunnels
• Services running on VMID 102
• No configuration conflicts

Solutions

Solution 1: SSH Tunnel (Best for API Access)

# Terminal 1: Start tunnel
./setup_ssh_tunnel.sh

# Terminal 2: Use API
PROXMOX_HOST=localhost python3 list_vms.py

# When done: Stop tunnel
./stop_ssh_tunnel.sh

Pros:

• Works for API access
• Secure
• Uses existing SSH access

Cons:

• Requires SSH access to Proxmox host
• Two terminals needed

Solution 2: Cloudflare Tunnel (Best for Web UI)

Access Proxmox web interface via:

• https://ml110-01.d-bis.org
• https://r630-01.d-bis.org
• https://r630-02.d-bis.org

Pros:

• Works from anywhere
• No SSH needed
• Secure (Cloudflare Access)

Cons:

• Web UI only (not API)
• Requires Cloudflare Access login

Solution 3: Run from Proxmox Network

Copy scripts to machine on 192.168.11.0/24 and run there.

Pros:

• Direct access
• No tunnels needed

Cons:

• Requires machine on that network
• May need VPN

Solution 4: Shell Script via SSH

export PROXMOX_HOST=192.168.11.10
export PROXMOX_USER=root
./list_vms.sh

Pros:

• Uses pvesh via SSH
• No API port needed

Cons:

• Requires SSH access
• Less feature-rich than Python script

Tunnel Management

Check Status

ssh root@192.168.11.12 "pct exec 102 -- systemctl status cloudflared-*"

Restart Tunnels

ssh root@192.168.11.12 "pct exec 102 -- systemctl restart cloudflared-*"

View Logs

ssh root@192.168.11.12 "pct exec 102 -- journalctl -u cloudflared-* -f"

Test Tunnel URLs

curl -I https://ml110-01.d-bis.org
curl -I https://r630-01.d-bis.org
curl -I https://r630-02.d-bis.org

Recommendations

1. For API Access: Use SSH tunnel (setup_ssh_tunnel.sh)
2. For Web UI: Use Cloudflare tunnel URLs
3. For Automation: Run scripts from Proxmox network or use SSH tunnel
4. For Monitoring: Use tunnel health check scripts

Next Steps

1. Test SSH tunnel: ./setup_ssh_tunnel.sh
2. Verify tunnel URLs work in browser
3. Use appropriate solution based on your needs
4. Monitor tunnel health regularly

Summary

✅ Tunnels: All configured correctly, no conflicts
✅ Configuration: .env file properly set up
⚠️ Network: Segmentation prevents direct access (expected)
✅ Solutions: Multiple working options available
✅ Scripts: All tools ready to use
