When your servers span on-premises data centers, heterogeneous clouds, and multiple virtual private clouds (VPCs), exposing public IP addresses for O&M creates security risk. Purchasing leased lines eliminates that risk but adds cost and setup time. Proxy mode — part of Bastionhost's network domain feature — removes both constraints: it routes O&M traffic through a proxy server in each isolated network, keeping all hosts off the public internet and requiring no dedicated circuits.
This topic shows you how to configure proxy mode to perform centralized operations and maintenance (O&M) on servers across heterogeneous networks.
Proxy mode requires Bastionhost Enterprise Edition.
