Link Aggregation (How to Set Up)

Hello,

I am new to networking and would like some guidance about how to set up.

My NAS offers four ethernet ports that can be used for Link Aggregation. I also understand that these need to be connected individually to a switch. At the moment, my NAS connects to my router. My computer also connects to my router.

What would be the set up with a switch in place? My understanding would be four connections for the NAS, another for my computer and one more that would connect back to the router.

Would this be correct?

Kind Regards
