Ah. No problem there then.

Yes. It has. DHCP is being provided by the WiFi Antenna.

eth0 in this case. eth1 is the interface to the ISP supplied Router.

So the references to OpenWRT is for when the NODogSplash system is being
installed on the ISP supplied Router. This was never considered to be an

Router.

My problem (as always with these things), is understanding the terminology.
