Simple UDP Proxy/Pipe application was designed to be an advanced UDP proxy/datapipe/packets forwarder and modifier with multiple functions.
Multiple clients allowed (you can connect many clients you want to this proxy), creation of ACP files (tcpdump capture files, just like a sniffer), packets forwarding (chat style, each packet is forwarded to all the other clients and server connected), packets injection (the tool opens a specific UDP port where you can send your customized packets which will be sent to the server), hexadecimal visualization and plugins support for the modification and visualization of the packets with some example plugins already included (Zdaemon huffman, Doom huffman, Half-life decoding and one for the replacement of the text strings).
Plugins (which work on both Windows and Linux) are very basic to create and use, just take a look at example_sudp.c for more informations .
