The mac address would be that of the router, I presume. But could I distinguish the ip addresses of the computers behind the router, or could I only see a global ip address that belongs to the router?
Using Scapy you can graph IP ID fields patterns to know how many distinct IP stacks are behind a NAT, but you may generally not be able to discover the IP behind the NATdevice. Here's a link to the page referencing it.
