XArp for Windows

A utility for detecting and blocking malicious network applications is the XArp utility. This utility can be used to prevent unauthorized access on a LAN or intranet. With a simple configuration file, any malicious application which uses XARP protocol can be prevented from using the given IP address.

XArp (elligent Routing Protocol) is an open source firewall that supports intelligent and BGP-based routing protocols. It can filter ICMP Echo Request (Echo) messages and ICMPbroadcast message (BGP) packets. If you are familiar with the standard Netscape router, XArp is comparable in functions to that of the traditional routers. But, it also offers a much wider range of functionality. In addition to the filtering function, this firewall also supports authentication, encryption, and protection against security threats and attacks.

XArp is able to protect corporate intranets, corporate networks, and local area networks (LANs). With a simple configuration, it is able to block and allow ICMP Echo Request (Echo) messages, ICMP broadcast packets, and BGP broadcast messages. The major components of XArp are the firewall, the scanner, and the filter modules. The firewall in this tool uses advanced techniques such as stream masking, congestion control, and policy-based filtering. On the other hand, the XArp filter has a built-in mechanism for traffic analysis and blocking.
