Assuming that we have a webserver hosted by us on our internal network as and we map it to pix outside interface ip address x.x.x.x as follows:

static (inside,outside) x.x.x.x netmask then any traffic from outside world hitting to x.x.x.x will directly be routed to Hence, we use port forwarding as follows:static (inside,outside) tcp interface 80 80 so that only the port 80 traffic destined to x.x.x.x should be forwarded to and not all the traffic. And you can also do by change the ISP cable to your device and reconfigure it .
