Click Options in the menu at the top of your screen. In the list that drops down click Preferences.
Click Pager tab at the top of this new window. You should now see the menu shown in the screenshot above. Enter a port number into the Pager Port box. It doesn't really matter what port you choose, but something between 10000 and 16000 would be a good idea. Please enter the port you chose into the box below.
Click the Security button near the top of the page.
Click the Application Monitor button near the left of the page.
We will list a series of lines here that will show you exactly how to setup Comodo Firewall's firewall for BYOND Dream Seeker. Go ahead and enter the settings shown below into the Network Control Rule menu.
