Free fbuilder software for linux

fBuilder project is a web-based utility for building and configuring your iptables or ipchains based Linux firewall. Written by the author of fwconfig, our fBuilder product line brings you many new and exciting features that will fit your firewall creation needs.
InnerTek Software currently offers two versions of fBuilder: fBuilder Lite - a free, ipchains only version of fBuilder that includes a standard set of features and fBuilder Plus - includes edit, insert, and delete capabilities for firewall rules, automatic back traffic rule creation, log reporting and export capabilities.
Our fBuilder products are also great for administering existing firewalls. When started, fBuilder will detect your running firewall and allow you to save it to a file. From that point, you can modify your firewall with the expert add utility or by using the edit/insert capabilities of fBuilder Plus.
