You need to implement Active/Active explicit proxy with high availability.
Note: This article uses Proxy1 and Proxy2 as examples.
To have Active/Active explicit deployment with high availability for ProxySG appliances, you must balance the load of traffic from the source and then configure failover groups on each proxy.
Configure the clients to send an equal amount of traffic to each proxy using one of the following methods:
To have high availability, make sure that each proxy is able to process the traffic of the other proxy when it is down.
Configure two failover groups on each proxy:
In this example configuration, the following could occur:
Implement Active/Active explicit proxy with high availability for two proxies, Proxy1 (IP address 10.10.10.1) and Proxy2 (IP address 10.10.10.2).
