Can i use a custom port for the docker neoload-loadgenerator port?

I'm running a neoload farm via docker/docker-compose and i need to spawn 2 loadgenerators on the same server.
In the second one i'm setting the LG_PORT env variable to 7110 and publish the related port but the LG doesn't pop up on NeoloadWeb.

(simplified) docker run command: docker run -p 7110:7110 -e LG_PORT=7110 neotys/neoload-loadgenerator

Despite my port settings this the LG log

2021/03/23 11:58:31 INFO - neoload.agent.Agent: Start transport API server on port: 7100
2021/03/23 11:59:51 FATAL - neoload.agent.Agent: Can't create server socket. port 7100 java.net.BindException: Address already in use
