Firewall and port settings before you install LEAPWORK

Before installing LEAPWORK in an distributed environment user should make sure that port 9000, 9001 on controller and port 6777 on agents machine are open and user is able to make telnet connection to them. So, in case user is running on secure or cloud environments like Amazon, Azure then they need to make sure that TCP ports 9000, 9001 and 6777 (both inbound and outbound) are open before running LEAPWORK.

Here is short description of how LEAPWORK use these ports.

Controller port

Studio and the Controller always communicate using internal API calls, and this requires the use of a TCP port. The default is port 9000, which you can change to any other port number that is not in use by other software on your computer. NOTE: Unless it is necessary for any particular reason, we do not recommend changing either the Controller, Controller API or Agent port numbers.

Controller API port

For any integration effort, access LEAPWORK’s open REST API using the port number set here. The default is port 9001, which you can change to any other port number that is not in use by other software on your computer. NOTE: Unless it is necessary for any particular reason, we do not recommend changing either the Controller, Controller API, or Agent port numbers.

Agent port

Automation flows run in the Agent, which communicates with Studio and the Controller through a closed remote-control protocol on a specific TCP port. The default port is 6777, which you can change to any other port number not in use by other software on the computer. NOTE: Unless it is necessary for any particular reason, we do not recommend changing either the Controller, Controller API, or Agent port numbers.
