SuSEFirewall2?

I have a linux box running firewall and masquerading, when I boot I get this message: Warning: FTP/IRC/Realaudio etc. masquerading does NOT work with ipchains and the 2.4 kernel. Either move to a stable 2.2 kernel or use SuSEfirewall2! The only copy of firewall2 that I can find is a beta version (SuSEfirewall2-1.7-0.noarch.rpm), is this the only version available or is there a complete version now available? If so, where can I download it from? Rich
