Okay, I'm thinking that I should start being concerned about security. I remember that when I first joined plug that there was pretty consistantly a thread or two going on monthly about iptables.Well, that/those threads stoped and nothing has replaced it. I was surfing and happened upon a forum geared mainly towards windows users with a small Linux section. They keep saying that all users need to be concerned about security and that if you are on a buntu system to start ufw. I then remembered MS Kachold walking me through setting up ufw (thanks Lisa). Now, I have ufw enabled and I set a rule allowing everything into my home computer  that is sent in on ports 22 and 23 I think these are the ssh & scp ports). The limitation (maybe) of gufw (the x interface for ufw) is that you can't set a range of addresses to allow data to be sent from another computer. The wiki for gufw really is really BAD!
