<quote>You can make it a gateway and router if you want...but it isn't necessary.</quote>
But it is by default based on the default dhcpd.conf file that it uses.
As a feature request: can there be an extra line or two on the network setup section of the admin website where the use specifies where the dhcpd is on or off that allows for configuration of the default gateway and dns, so the users don't have to drop to a terminal to correct this? And, during the initial setup, ask the installer if the core will be between the users and internet or just on the network, and have the wizard configure it accordingly.
