6.1 IP address

The IP address of the host has to belong to the same network as the IP address of the fli4l router (on the Ethernet interface), for example 192.168.6.2 in case the router has the IP address 192.168.6.1. IP addresses have to be unique throughout the network, so it's a good idea to change (only) the last number. You will also have to make sure you specify the same IP address as specified in the file config/base.txt.
