Intervlan not working DELL N1524

Hi I am currently having issues to communicate InterVlans. My network starts from the Switch on the shown image. 

As you can see I have created three Vlans with devices connected to a Switch N1524. I have already created the VLANS, and applied the ip routing command, but I cannot communicate with devices on the other subnet. The router shown on the pic is from the ISP which is providing a data link from other sites. 

Although I havent added all the devices yet, here is a copy of the current configs:

For testing purposes I have on the Gigabit 1/0/3 (Vlan10) connected my laptop which is configured with 10.15.1.51 /24 including the gateway, and the other computer on the gigabit 1/0/7 (Vlan23) With 10.1.23.11/24 including the gateway. 

On the interface Gigabit 1/0/24 is the cable connected to the router of the ISP.

I appreciate your time to help.
