BitLord chooses a random port to listen on when you install it. Before we can open ports for BitLord, we need to find out what port BitLord is using. Go ahead and open BitLord.
In the menu at the top of your screen, click Options. Clicking Options will cause a menu to drop down. In this new menu click Preferences.
In the menu on the left the top option Connection should be selected. On the right hand side of this window you should see a Listen Port option. That is the port that you need to open. You can change it if you like. Please enter the listen port below.
There is one more thing we need to do. We need to shut off the UPNP of BitLord.
In the menu on the left hand side under Advanced, click Connection. There should be an Enable UPnP Port Mapping(XP only) checkbox on the right hand side. Make sure it is unchecked.
Click the Firewall link near the left hand side of the page.
Click the Expert link near the top of the page.
We will list a series of lines here that will show you exactly how to setup Zone Alarm's firewall for BitLord. Go ahead and enter the settings shown below into the Add Rule menu.
When you are finished, click the Apply button at the bottom of your screen. And that is it! You are done!
