Enterprise HAProxy load balancing & traffic management
Provision dedicated HAProxy Load Balancer nodes directly from Virtualizor. Route Layer 4 (TCP) and Layer 7 (HTTP, HTTPS, HTTP/2, HTTP/3) traffic, manage SSL/TLS termination with a reusable certificate store, monitor live HAProxy stats & logs, and configure host-level domain forwarding with automatic failover.
Dedicated load balancer nodes & backend VPS pools
Deploy HAProxy instances directly from Virtualizor to distribute web and TCP application traffic across pools of backend virtual machines.
- Layer 4 (TCP) & Layer 7 (HTTP/HTTPS/HTTP2/HTTP3) proxying
- Source-to-destination port mapping rules (e.g., 80→80, 443→8080, 3306→3306)
- SSL/TLS termination with 1-click self-signed or custom certificate upload
- Reusable certificate store across multiple load balancing rules
Four simple steps from listener to backend pool
Provision HAProxy load balancing instances and forwarding rules directly inside Virtualizor.
1. Provision LB Node
Create a dedicated Load Balancer VM instance or configure host-level HAProxy domain forwarding for shared IP nodes.
2. Define Protocol & Ports
Select source protocol (HTTP, HTTPS, HTTP/2, HTTP/3, TCP) and map source ports to target destination ports.
3. Configure SSL & Certs
Generate self-signed SSL certs in 1-click, upload custom CRT/KEY/Chain, or reuse existing certificates from the store.
4. Attach VPS Pool & Monitor
Assign backend target VMs. Virtualizor runs automated health checks, logs connections, and reroutes traffic on failure.
Enterprise traffic management
Full control over load distribution algorithms, SSL certificate storage, live analytics, and host NAT forwarding.
HAProxy distribution algorithms
Configure HAProxy algorithm rules tailored to your application traffic - Round Robin for web pools, Least Connections for heavy database queries, or Source IP Hash for sticky user sessions.
- Round Robin (roundrobin) sequential routing
- Least Connections (leastconn) active request balancing
- Source IP Hash (source) sticky session affinity
SSL/TLS termination & cert store
Offload SSL encryption at the load balancer to free CPU resources on backend VMs. Auto-generate self-signed certs or upload custom certificates to the central reusable store.
- 1-Click Auto Self-Signed SSL generation
- Custom CRT, Private KEY & CA Chain upload
- Reusable SSL Certificate Store (lb_ssl_certs DB)
Live HAProxy stats, logs & NAT forwarding
Inspect real-time HAProxy traffic throughput, active connections, and live logs directly inside the panel. Support host-level domain forwarding (NAT) for private-IP VPSs.
- Real-time HAProxy traffic stats (lb_get_stats)
- Live connection log stream (lb_get_logs) & health checks
- VPS Domain Forwarding & NAT for shared public IPs
