open outbound HTTP connections to the server address (the same address you use in the browser to view the TeamCity UI).The agent process (java) should be able to: If the agent is behind NAT and cannot be accessed by any of addresses of the agent machine network interfaces, please specify the ownAddress property in the buildAgent.properties file. the addresses of the network interfaces on the agent machine.If a proxying server is used, it must be correctly configured. the source IP of the HTTP request received by the server when the agent establishes a connection to the server.the address specified in the ownAddress property of the buildAgent.properties file (if any).The port is determined using the ownPort property of the buildAgent.properties file as the starting port (9090 by default), and the following IP addresses are tried: Unless the unidirectional agent-to-server connection supported since TeamCity 9.1 is configured, the server should be able to open HTTP connections to the agent.An agent should be able to open HTTP connections to the server using the server address specified in the serverUrl property (usually the same URL as server web UI).Please note that in order to run a TeamCity build agent, the user account used to run the Agent requires the following privileges:

For production installations, it is recommended to adjust the Agent's JVM parameters to include the -server option.Ä«efore the installation, please review the Conflicting Software section.If you need the agent to run a operating system different from the TeamCity server, perform the procedure described below.If you need more build agents, perform the procedure described below. This is not a recommended setup for production purposes because of security concerns and since the build procedure can slow down the responsiveness of the web UI and overall TeamCity server functioning.
