Ports 80 and 433


Recommended Posts

Port 80 and 443 refer to the REMOTE port. You will see that port as the remote port if someone is using it as their listening port (as most websites do). The port used on YOUR computer will typically be in the 1024-5000 range, as that is the ephemeral port range.

Firewalls typically check for the remote port.

While it's not normal to see the port being used for BT connections, it is possible. Many trackers actually do run on port 80.

However, you shouldn't see established -incoming- connections to port 80 or 443 unless you explicitly set it to listen on that port.

The listening port is technically passive in the sense that it waits for connections, but it will actively send back on that same port to an established incoming connection.
