Hi, I think you have something else running on port 80 then. You can check this with "netstat -an | grep 80" Maybe apache is running on that port. Only one application can listen on a port at a time.

I already tried to install the Squid proxy and running well. But, I can not use port 80 to accept connection from users, but If I used other port like 8080 or default port 3128, it working fine. Anybody can suggest me, what kind of configuration I have to do. Thank you so much. Chris
