Nat Probe very usefull program, try to sends ICMP packet out the LAN, and detect all the host that allow it. With this you can find bugs in your network ( or others), for example hosts tha allow p2p connections.

When we use a Gateway, we send the packets with IP dest of the target, but the dest mac on the ethernet is the mac at the Gateway. If we send a packet to the diferents macs in the lan, we can know who is the gateway when we recive an response from this mac.

Some times we can discover more than one box configured to be an gateway, generally, this is an wrong configuration, and the box will response with an ICMP-Redirect. This is the same, becouse the script only verify if the mac response.

How does Nat Probe work

It sends ICMP packets in controlled manner and detects natted IP and routers . This tool helps in network penetration testing as we can switch between internal IP and reach diffrent network to gain access.

Operating system supported

*nix systems.

Source code is also available.
