Thanks for the fast reply.
OK thanks for clarifying about the WAN IP of the router, as I did have that as a different IP.
I still cannot ping the device (I'm actually testing with a simple PC to ensure nothing strange in the device complicates things).
Here is my network:

config interface 'loopback'
	option ifname 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'
