While the default connection port for the Sysdig agent is tcp/6666, this may impose a limit or delay testing in some companies with strict security policies.
You can optionally configure the agent to communicate with Sysdig Monitor back-end servers over port tcp/80 with the following parameter in the agent user settings configuration file /opt/draios/etc/dragent.yaml:
Append the parameter to the containerized agent's dragent.yaml file with:
docker exec -it sysdig-agent bash
echo collector_port: 80 >> /opt/draios/etc/dragent.yaml
then restart the sysdig-agent container with
docker restart sysdig-agent
For a native agent installation use only the above `echo` command then:
service dragent restart

Once the agent is restarted, it will communicate over port 80 and SSL will continue to be used as it was with the default port 6666.
