Having a firewall is a good thing since it protects you from the whole plethora of dangers lurking in the dark corners of the world-wide network. You must also open your designated listen port on all of your firewalls, to permit new INCOMING traffic through. That's necessary but it's only half of the job. This is usually caused by a software/hardware firewall or/and a NAT router (or any combination or those) sitting between you and the Internet.Īdding BitComet to your software firewall permits BitComet to send outgoing traffic (and replies to it) through the firewall to the Internet. That means you can initiate and establish connections to other peers but others cannot establish connections to your client (well they can initiate them, but they won't reach you).
If the status light on the right hand lower corner of BitComet's window is yellow and the text next to it says “Blocked”, then inbound connections to your computer are being blocked.
