The following ports must be enabled bi-directionally to connect with the Load Generator:

1. The port (by default 54345) used for communication between the loadgenerator and Controller.

2. Ports: TCP (54245, 54345)

If your environment includes an HTTP 1.0 proxy server using NTLM, make sure to enable the port defined in the network profile for communication with the loadgenerator machine, in order to bypass the NTLM authentication.
