How to do it again? I had simply forwarded needed ports (e.g. for counter strike, ftp, http etc)) but now with same system, same OS and same router and settings, it's not working. Tried setting router to "factory defaults" and do everything again. However other jobs are being done like it is connecting to my DSL ISP and I can access Internet easily. Still no success. PS. I tried on both Windows and Ubuntu. On Windows I use it for Counter Strike and others (e.g. host my local FTP server) on Ubuntu.
