Free ip packets software for windows

Packet Spy is a free and useful packet sniffer utility.
Packet Spy is a tool designed with the purpose of monitoring incoming and outgoing packets from a given network. It is most useful in situations where you need to verify the security of a packet or monitor the responses invoked by the network.
It features an onscreen view of sent/received packets and can also log results to a file for further examination.
Main features:
- Displays incoming and outgoing packets from a given source
- Create filters to monitor for specific traffic
- Output reports to log files for further examination
- Displays IP/TCP/UDP packet header information

Determinate the route packets travel across an IP network with SI Trace tool. If you cannot connect to a computer over a network, there might be something wrong with the remote PC or with your Internet connection. Or your router might need a reset.
Or your Internet provider could be having a temporarily problem that theyll eventually solve. Or maybe its the fault of one of the routers, switches, access points, servers, or other network hosts that are in between you and the remote computer. How would you know for sure?
In the beginning of the Internet, a tool called traceroute was introduced in Unix. Traceroute does exactly what its name suggests: it traces the route of IP packets while they travel from your PC to the remote destination.
SI Trace will allow you to see exactly where the connectivity problem is, no matter how far it is from your computer. The last host to respond to traceroute is the last host that is working properly. The first one that fails to respond is the faulty one.
Usually you would get a response right in the console window in a matter of seconds. You get the response in a Spartan-looking black console window.
While theres nothing particularly wrong in using the supplied tracert.exe, we at Soft Institute wrapped the same thing into a much more convenient package.
SI Trace provides clearly legible, well-formatted output by providing easy to understand numbers and well-explained results. It displays all the vital information from classic Unix traceroute and Windows tracert commands, and allows you to check more than one computer by simply selecting the address from a combo box. Thanks to its user-friendly interface, it is much more convenient to use than Windows tracert.

IP Relay 1.0 offers you a small yet smart program that can be useful to relay/tunnel TCP and UDP connections received on a local IP port to a remote IP port. This gives the ability to tunnel TCP and UDP packets through an intermediate host. The program works both on Linux/Unix and Win32 platforms.

Alchemy Traceroute is a free and graphic replacement for the standard traceroute utility. The program will show you IP packets traced from your local computer to the host you have entered.
