Join Proxy is a Primary Server or a Satellite with the Join Proxy role that acts as a proxy by accepting and maintaining connections from Windows managed devices that are in a private network.
NOTE:For an agent initiated connection, remote management through Join Proxy is not supported.
Figure 1-2 Remote Management Join Proxy - Satellite Server with Join Proxy role
Join Proxy satellite server allows multiple Windows devices that are in a private network on the other side of a firewall or router that is behind NAT (Network Address Translation) to connect to it for remote management operations. Fore details, see ZENworks 11 SP4 Primary Server and Satellite Reference.
NOTE:During the rights-based Remote Management, at least one primary server (DMZ or non-DMZ) should be reachable from managed device to validate the authenticity of the connection.
Join Proxy when used for remote management operations joins two connections together. The first connection being the one that the managed device maintains with the proxy server while the second one is the connection that comes from the viewer machine of the administrator.
