Hi to all!. I some time ago bought new laptop and installed windows, and i have many problems that i wanted to resolve, but i don't know how. I was using windows 10, but i've installed windows and i think that there are some issues with firewall. I can't use postgresql port because it's often busy and some ports are not visible to other clients from the internet. May be, it is a problem with router, but I'm not sure. So what is your opinion?
