Hello All

I am new here so please bear with me . I have a question please could you point me to the correct direction. Have a look at the below diagram. I want to achieve the below – this is not in place yet but this is what I want to achieve.

My question is – what configurations do I need done on the Layer3 switch in other to pass through internet to other switches (SWA,SWB,SWC) from my ISP

Thanks guys for your help.

Firewall is facing your ISP?  

So what kind of WAN network are you getting?

Actually it's not directly facing the firewall -  

mistake in the diagram

the ISp is connected to their radio and that is connected to the firewall device. 

Thanks for your help
