How to Change an ISA Proxy Port

Microsoft Internet Security and Acceleration (ISA) server is an application you add to your Windows server to control Internet services. ISA proxy services run on the default proxy port, which is 80. Port number 80 is the web services port, so users connect to the proxy server and then connect to a web host server to view web pages. Changing the proxy server port adds security for the server, because proxy scanners are unable to find it using the default port.

  Click the Windows ISA server's "Start" button in the taskbar. Select "Administrative Tools," then click "ISA Server" to open your main configuration console.

  Right-click your server name on the left side of the window and select "Properties" from the pop-up menu. This opens a configuration window.

  Click the "Outgoing Web Requests" tab. This shows your current proxy port settings for your users. Type your new port in the "TCP Port" text box. For instance, a common alternative port number for a proxy server is "8080."

  Click "OK" to save your settings. Right-click the server name again and select "Restart" to restart the server services, so the changes take effect.
