Configure Boomerang to use a proxy server
Go to the ‘Manage Settings’ page by clicking ‘Settings’ at the top of the page.
Scroll down to the ‘Proxy settings’ section and click ‘Use the following proxy settings’.
Although Boomerang communicates with any external resources including AWS and your VMWare environment through the proxy, bulk data transfers (e.g., reading VM snapshots data from vSphere on replication and restoring VMs on copyback) happen directly over TCP and automatically bypass your proxy server. Please make sure that the Boomerang appliance can communicate with the ESXi servers where VMs are operated without a proxy.
