First make sure the windows box port 80 can be accessed from your Linux box: 1. log on to your linux box 2. telnet windows-box 80 Then, make sure your Linux box port 80 is accessible from the Internet: 3. go to http://centralops.net/co/ 4. use the "tcpquery" function to do a http query on your Linux box Then, configure iptables on your Linux box. Configure to log port 80 rejects and redirects. Use the logging info to make sure the packets are being redirected. mike On Mon, 2003-07-14 at 11:10, Jorge UmaÃa wrote: > I have a LINUX box with a public ip.
