Firewall Builder : Is a flexible and powerful tool that allows you to build firewall configurations and policies for multiple firewalls/machines based on iptables, ipfilter, OpenBSD pf, Cisco ASA & PIX, or Cisco FWSM. fwbuilder uses objects and functionality like drag-and-drop and search-and-replace to help ease configurations. You can install the fwbuilder on a separate machine and then either manually transfer the configurations or securely deploy via SSH or SCP.
