Hi,
We have a small ntwork in our office, (something like 15 clients, my server (for ftp),a IIS server and 2 network printers….so not big at all, should be dead easy to identify anything on it and know where they are.
Past couple of days we had a few security issues, so I’ve been reviewing logs from the router (BT Business 2Wire).
Since a few days ago I have come across 3 devices that I have no idea what or where they are but they are (according to the router)there and even have been assigned public IP’s, the very same ones that are assigned to servers, (due to security reasons I keep servers IP’s locally since I only need them to communicate with PC’s on the same network) and give them a secondary public IP’s I use for remote connection from my house. Anyhoo I come across these three devices;
Name: DETECTIVE
IP:0.0.0.0
they all have their individual MAC addresses which does not match anything I have in the office, and does not come up on arp, you can see they have been assigned public IP when you go in to NAT and Address Allocation.
Any feedback is apprciated,
Cheers fellars and hi.
