The testing window repots me that port is not opened.
But the connetction icon highlights in green.
If i use "Port Forward Network Utilites" and check the port - it says that port is opened (forwarded) and all is fine.
Port forward setup is configured on my linux debian server via "iptables -t nat -A PREROUTING.... bla-bla-bla"
It forwards many other ports to local machines. So there is all fine with my setup.
System is Windows 7_64
PS. And there is permanent error (screenshot #3) on any BitTorrent program restart.
