Cause if you want to be in active mode you have to type IP address but when i type my real IP address it does not work.
So may i change from private address to real IP or is it because i got router/modem?
Yes, this will be why.

To be able to use your real IP address you may need to look at your router settings.

My router describes this as a 'Virtual Server' and it allows you to map ports from the internet to ports on the internal network.

Hence : To map tcp port 22 you would set up a virtual server entry thus:

ID-1 Public Port-22 Private Port-22 Port Type-TCP Host IP Address-10.0.0.1


You need to know which ports to map for your P2P and to examine the settings for your router.
