This seems straightforward, but I"m having trouble finding an answer.
I'm trying to map a private network behind a NAT. Someone in the Lab setup a NAT router that everything is behind, but that person is long gone and they don't have login credentials for the router anymore. I'm trying to map the network (PCs/Macs and ethernet-connected Research apparatus). If it was just PCs.. I'd go computer to computer and pull the MACs.. it's the network'ed lab equipment that's harder to inventory.
I've got at least a partial inventory of devices by IP. I'm looking to find MACs for these devices so we can setup DHCP reservations on a new router.. since I can't log into the existing one to see what they did.
I plugged in, started a packet capture, and nmap'ed some IPs to generate traffic. What I'm looking to do is generate a report... or filter.. that will show me IPs w/ corresponding MACs.
I've found a few so far by just searching through the whole log for IPs (sender).. opening the packet capture and searching for the source MAC.. but that's proving tedious.
Is there any way to display all IPs with corresponding MACs from the Capture?
Thanks, Steven.
