Is there a way to block ports. I would like to disable the mail server and then block ports 25, 113, and 443. The SME server is being used for an internet firewall at an ISP. It is only being used to allow access to a website. We just need 80,21, and two ports for PCAnywhere. We would like to block the rest. If possible a script so that if for some reason the server reboots the ports remain blocked. Thanks.
