I finally have the firewall up but after doing an nmap localhost I found several ports open that should not be.
Don't do an an nmap against the localhost. You'll get a completely misleading result. The firewall only protects against connections from other machines, not from connections from itself. So, as an example, even though my firewall blocks port 515 I'm still perfectly able to print fron localhost. Even though I block port 80 I'm still perfectly able to browse my local pages from localhost. If you want to verify your firewall, find another machine and nmap from there. regards Anders
