Firewalled Environment

boom will work in environments with Inbound or Outbound only firewall settings for the Server - Agent Connection.

Firewalled boom Server (Outbound)

If a Firewall blocks the incoming traffic on the server port 23020, the boom Agents can not actively submit any information or data to the server. The Server will switch to a polling mode and fetch the data from the Agents.
Fresh installed boom Agents can not announce their presence to the boom Server. Therefore the administrator has to add such Agents manually in the GUI with the correct IP Address. The remote Agent must be running. After entering the Agent's IP address the boom Server will initiate a request to this boom Agent to retrieve all necessary information.
If the Agent resides on a system with changing IP address (e.g. DHCP) it must be ensured that the Agent's address can be resolved by DNS.

  

The successfully connected Agent will be automatically approved and placed in the appropriate OS type folder with resolved hostname and other attributes.

Firewalled boom Agent (Inbound)

If a Firewall blocks the incoming traffic on the agent port 23021, the server can not actively send any request to the Agent.
Every fresh installed boom Agent will send a request for approval to its configured boom server.

 

After the approval the boom Server will try to reach the agent and might need up to 20 seconds to recognize that this is a firewalled agent and change the icon in the Hosts View.
As soon as the boom Server marked an Agent as firewalled the communication protocol will be switched to a listening mode and the Agent will poll data and requests from the server. In this mode the server will continue to try to reach the Agent.
To avoid that the Server tries to actively establish a connection to the agent, open the Agent Details by double clicking on the Agent. Clear the Firewalled checkbox to reset this auto-detected firewalled state and press Save. Then set the Firewalled checkbox and press Save. This sets the Agent to the manual firewalled state. No more heartbeats or other kind of connections will be initiated from the boom server.

Remote actions in this firewall mode will have delays up to 5 seconds, before the Agent polls them from the server.
