Yup. If you don't think you can take Gizmo's word (well you should LOL), then I would hope you would take my word... Smoothwall is a nice one. Yet in all truth there are SEVERAL, firewalls out there. A lo and I won't name them all. They are free, some you need to pay, some easy, some hard. Do some exploring. Besides finding a good safe firewall, also need one that fits your needs and what things you work with. Anyquestions you can drop em by. Just of heads up I will be out until sunday afternoon, I'll then check back.
