Graphical front end for iptables

Hello Linux folkz, Does somebody know if there any graphical front end application for configuring iptables filtering and masquerading. The problem is that after upgrading to kernel 2.4.7 I need to setup masquerading for my internal network. I configured external firewall by writing iptables rules in executable bash script which is executed upon system bootup. Now there is the challenge to configure a proper firewalling. Could somebody point me on a proper link or resources for this matter. Thank you in advance.
