Version release notes
New Features & Improvements
- DNS support for Layer 7: Hostnames may be used as the address for a Layer 7 Real Server. HAProxy is now made aware of changes made to the DNS Settings via the WebUI.
- SSH Root Access: Configuring root SSH access via the WebUI on AWS is now possible to facilitate HA pairing on that platform.
- Update Check: An online update check is made immediately after running initial setup so that the result is immediately available when logging into the WebUI for the first time.
- Setup CLI: The initial setup program lbsetup (and its alias lb_net_setup.php) now accept named arguments which allow the user to pass all the data that they can interactive-mode.
Bug Fixes
- GSLB: The GSLB service now checks for and starts all missing, required services on reload instead of requiring the user to restart the GSLB service manually the first time they configure the GSLB service.
- WebUI Accounts: Passwords for WebUI accounts are now synchronised in both directions on pairing appliances. Nodes will now keep their existing passwords in all situations, previously passwords from the secondary node would overwrite those on the primary node in the case of a conflict.
- AWS HA Failover: Local modifications to the contents of the azhaFailover script will be preserved across upgrades. The script is now included in backups and Technical Support Downloads.
- WebUI Styling: Fixed styling issues which resulted in non-purple title-bars for some modals.
- WebUI Styling: Fixed styling issues on the SSL Certificates page.
- WebUI Styling: Fixed styling issues where the Freetype field in the Edit ACL modal was unhelpfully small.
- PFX Certificates: It is now possible to upload a PFX certificate with a space in its name.
- Bonded Interface Restore: Previously restoring to/from a configuration that used bonded interfaces resulted in a running configuration that might not match the on-disk configuration, this is no longer the case.
- SNMP Engine ID: Some appliance images shipped with an SNMP Engine ID pre-configured. Restoring the appliance to factory defaults now clears the SNMP Engine ID.
Security Updates
- SSH Forwarding Mitigation: All forwarding methods are now disabled by default to mitigate CVE-2025-32728.

Outstanding Load Balancer Quality and Support
Reviewed on Feb 26, 2026
Review provided by G2
What do you like best about the product?
We have been using Load Balancer products for several years now and we are completely satisfied with the quality of the products and especially the quality of the support team. Support has been outstanding during the few times we needed help with our WAF. The WAF is easy to use and just runs constantly without causing us any problems. It was easy to integrate into our network due to the collaboration between Metaswitch and Loadbalancer.
What do you dislike about the product?
I don't have any dislikes regarding our Load Balancer. It works exactly as we expect and rarely needs any maintenance.
What problems is the product solving and how is that benefiting you?
We had quite a lot of hackers trying to access our Metaswitch before installing our Loadbalancer WAF. Sometimes a few were successful at retrieving config files from our Metaswitch. Since the WAF was installed, we have not had any further issues with hackers.

Load Balancer support team
Reviewed on Sep 08, 2025
Review provided by G2
What do you like best about the product?
The load balancers themselves have worked well, and whenever there are questions on specific functions for some new implementations, their support team is very responsive, knowledgeable, and friendly. There are times when you need to work off-hours and their support team have helped me through these times. I've had to contact them through new load balancer additions, configs on new additions, and most recently upgrades that needed a new cert, each time working with support has made the process flow smoothly and easily.
What do you dislike about the product?
During some maintenances for a VIP, draining the connections can take some time with certain configs, would be nice if it was quick for all types. I'm sure it could be resolved by reconfiguring the VIP but changes like that aren't high priority since its just during maintenance windows.
What problems is the product solving and how is that benefiting you?
Helps us load balance our applications and services with high uptime. This helps also with any maintenances, and upgrades that may be needed. Running an Active and Passive set also helps with redundancy and high uptime for our critical applications.

Review provided by G2
What do you like best about the product?
We've used Loadbalancer.org's appliance extensively for TCP load balancing, SSL offloading, and both Layer 4 and Layer 7 load balancing. What stands out is how simple and fast it is to operate. The web interface is clean, and all the essential features are easily accessible without having to dig deep into complex menus. Despite the simplicity, it also supports more advanced configurations for those who need them. We've deployed it in AWS with high availability, and HA has worked flawlessly. Overall, it's been rock solid and reliable in production.
Their support is excellent—they reply quickly and are very knowledgeable. We also deployed the appliance via a CloudFormation template in AWS, and the process was very easy.
Setup of new virtual services is also very easy. I especially like the clone option, which makes it simple to add new ports based on existing configurations.
I also like the logic of how it recognises that the backend server is the same, even across multiple ports, and offers to disable all ports for that backend server—this is very helpful during maintenance.

What do you dislike about the product?
While the core functionality is excellent, visibility during issues is limited. The logs, reports, and graphs are fairly basic and lack deeper insight. Email alerts are not very customizable—you either receive too much or miss what you actually care about. This isn't a major problem when things are running smoothly (which is almost always the case), but during a troubleshooting scenario, you'd want more granular monitoring and alerting options.
What problems is the product solving and how is that benefiting you?
It provides reliable load balancing across multiple application servers, which ensures high availability and performance for our services. The ability to recognize backend servers across multiple ports and offer to disable all related ports during maintenance is especially useful, making the process safer and more streamlined.

Reviewed on Jun 19, 2025
Review provided by G2
What do you like best about the product?
We recently implemented Load Balancing (LB) in our platform solution and wanted to share our experience. The Application Delivery Controller (ADC) has greatly enhanced performance consistency, even under high traffic conditions. By efficiently distributing incoming traffic, it has significantly reduced downtime and eliminated bottlenecks across our critical services.
The management dashboard is clean and intuitive, making it straightforward to configure load balancing rules, health checks, SSL offloading, and more. The solution has also scaled seamlessly as our traffic increased, supporting both horizontal and vertical scaling with minimal effort.
The documentation is thorough, and the support team has been exceptionally responsive. What truly stood out was the level of dedication from their team—they not only provided suggestions and recommendations, but also tested our solution in their own lab environment to offer a tailored fix. This is a level of support and engagement we haven't experienced with any other NLB vendor.

What do you dislike about the product?
The licensing and pricing model can be somewhat opaque, particularly when scaling out or enabling premium features. A more transparent and detailed breakdown would greatly assist with budgeting and capacity planning. Additionally, configuring advanced features—such as custom health checks or content switching—can be challenging without comprehensive documentation or prior experience. While the built-in monitoring tools offer basic metrics, gaining deeper operational insights typically requires integration with third-party monitoring solutions.

This implementation has proven instrumental in addressing several key challenges and delivering measurable benefits across our services.
Improved Availability and Resilience
One of the primary advantages we've observed is the significant improvement in service availability. The ADC ensures that incoming traffic is intelligently distributed across multiple backend servers, effectively eliminating single points of failure. This has enabled high availability for our critical web services, even under fluctuating load conditions.
Efficient Traffic Distribution and Scalability
By balancing traffic dynamically based on server load and health status, the ADC has allowed us to scale more efficiently. This is particularly critical in healthcare environments, where access to imaging and records must remain uninterrupted. As demand grows, the system adapts in real time, maintaining consistent performance without manual intervention.
Health Monitoring and Failover
Built-in health monitoring and automatic failover capabilities have significantly reduced unplanned downtime. In the event of a server failure or degraded performance, traffic is seamlessly rerouted to healthy nodes—ensuring service continuity and minimizing recovery time during incidents.
Operational Efficiency
Beyond technical gains, the ADC has also reduced the operational burden on our engineering teams. With centralized traffic management, automated failover, and better observability, we spend less time firefighting and more time focusing on innovation and service improvements.
Conclusion:
The integration of Load Balancer Enterprise ADC has been a pivotal step in modernizing our infrastructure. It’s enabled us to deliver a more stable, responsive, and resilient PACS platform to healthcare professionals, ultimately improving patient care by ensuring consistent access to vital imaging data
