Seems to demand connection to the Internet for DNS. The scenario is run net server in one namespace, and flent in another. Forward packets out and route between vlan's on an external box that is being tested. It works for basic iperf but not flent. # flent rrule -p all_scaled -l 300 --host=198.18.1.1 -t example -o example.png Started Flent 1.2.2 using Python 3.6.9.
