I thought packet filtering was at the data link layer, but now I'm second-guessing myself. I need to review those layers again!

I feel like I might confuse the layers. Wasn't there something about the transport layer being more about connections rather than filtering?

I remember studying that packet filtering is primarily done at the network layer. It seems to fit with similar questions we've practiced.

I think packet filtering happens at the network layer, but I'm not entirely sure. It could be transport too, right?
