Proxmox Disaster Recovery and Network Segmentation Design Designed a security-first Proxmox architecture separating VoIP, web, database, and management traffic with deny-by-default firewall policies. The solution uses HAProxy for web services, WireGuard for secure site-to-site connectivity, Proxmox Backup Server for off-site backups, and a standalone Contabo host for failover of critical PBX and escrow workloads.
