Just started using ApexDC 0.40 and have the same problem as expressed in this old thread.
Any port number I try, so far 15+ and port forward them on both TCP and UDP I only get UDP pass when checking connection, TCP always fail!
My firewall is turned off during these tests.
So why is it not possible to get the TCP connection right?
Can it have something to do with my ISP?
Read all the guides at this forum and tried to follow them to the point.
