At a command prompt, chmod u+x script ./script Saioa, it sounds to me as though you need to learn some Unix/Linux fundamentals, in order to tackle the other problems that will surely come up when you're building a firewall. I suggest that you get a good book about Unix or Linux, and read it. For an introductory book, lots of people like Running Linux, from O'Reilly. For an intermediate book, Unix Power Tools, also from O'Reilly, is terrific. Good luck, Andrew.
