Which is firewall generator suitable for new hand?

Hi All,

    I am a new hand in linux system. I want to set up a firewall in my 
debain in my home.  Which is the firewall generator suitable for a new 
hand in firewall? Since the document about iptables is too complicated 
for me, I could not use it.

    Could any one give me a suggestion?

Regards,
James Ng
