I’m using a computer that connects through a server running Microsoft Internet Connection Sharing (ICS). In the past, BitComet’s automatic port configuration worked fine, but now my BitComet listening port will not open. I have tried manually opening the port in the Windows Firewall on the computer running ICS but this doesn’t help. Neither the server nor my computer are running any other type of firewall. Any ideas?
Look in your log tab when BitComet starts up, and it may give you an idea of what’s wrong.
