Cube configuration is incorrect.  The third octet of your IP addresses is using .1 when your network appears to use .0.

First change the IP of the Cube from 192.168.1.254 to something in the .0 range that is outside your DHCP range.  Make sure it doesn't conflict with any other devices on your network already on 192.168.0.X.  Something like 192.168.0.50 should probably work.  Reboot the Cube first after IP change.  Then access it on the whatever the new IP address is using port 8000.  So in this example 192.68.0.50:8000.

Also you have a typo in the second value of Pool address.  The + sign.

So the correct values in the configuration would be -

IP: 192.168.0.50 (or whatever value you decide above)
Mask: 255.255.255.0
Gateway: 192.168.0.1
WEB Port: 8000
Primary DNS: 192.168.0.1
Secondary DNS: 8.8.8.8
Pool Ports: 8330,8330
Pool Addresses: 192.168.0.17,192.168.0.17
