Packet filtering, you say? Sounds like a job for the network layer, where the packets can't hide behind those pesky transport or physical layers.

Hmm, I think the firewall filters packets at the network layer. Gotta love those OSI layer shenanigans!

I believe it's at the Data link layer, as the firewall can also filter based on MAC addresses.

I agree with Sherrell, because the firewall examines the IP addresses and ports at the Network layer.
