You are welcome to use the GWLB service. GWLB (Gateway Load Balancer, GWLB) runs at the network layer, helping customers deploy, scale, and manage third-party virtual appliances such as firewalls, intrusion detection and prevention systems, analytics, and visibility, with simpler operations and stronger security.

GWLB processes traffic at the network layer and is independent of the status of the device. This design can be compatible with any third-party virtual appliance as long as the device supports GENEVE encapsulation/decapsulation and original data packet.
