Reapoff is an open-source filtering firewall that acts as an arbitrary protocol proxy with a focus on regular expressions.
Compared to packet filtering firewalls, proxy-based firewalls provide superior protection as they interpret each protocol instead of making assumptions based on TCP port numbers. By interpreting protocols, REAPOFF allows administrators to specify security policies on different operations offered by those protocols. For instance, an FTP proxy that protects an FTP server ensures that clients use only the FTP protocol and may specify a subset of commands that are allowed, such as disallowing uploads.
What sets REAPOFF apart from other proxies is its flexibility. As an arbitrary protocol proxy, it can work with any TCP/IP based protocol by modifying its configuration files. Adding new features or removing them becomes easy since new rules can be added or commented out as needed. It is important for system administrators to have a filtering tool that adapts to changing vulnerabilities. REAPOFF is committed to being the most intelligent proxy by maintaining a library of rules that add new functionality or protect against newly announced vulnerabilities.
