Re: [arch-general] Port 80 is shown open in port scan without any web server running

Are you sure that this IP is really your public one? The static IP which you do assign to your eth0 interface is from a private netblock. It looks like you create a tunnel on top of that connection with this strange Cyberoam client software. The output of "ip addr show" would be interesting. -- Regards, Richard Schütz
