Hello, my friends. I recently bought new computer and reinstalled windows, and i have many problems that i wanted to fix, but i don't know how. I used mac os, but i've installed win7 and i think that there are some problems with brandmauer. I can't use postgresql port because it's also not working and some ports are not visible to other computers from the internet. Perhaps, it is an issue with router, but I'm not sure. What do you think?
