Welcome to tracetcp.

tracetcp is a command line traceroute utility for WIN32 that uses TCP SYN packets rather than ICMP/UDP packets that the usual implementations use, thus bypassing gateways that block traditional traceroute packets.

In addition to providing the functionality of the standard traceroute utility tracetcp allows a trace to be performed over any TCP port. This allows the discovery of what ports a filewall blocks & and also the presence of any transparent proxies that have been put in place.
