Hello, my friends. I some time ago changed my computer and reinstalled operating system, and i have some issues that i wanted to resolve, but i don't know how. I was using ubuntu, but i've installed windows and my opinion is that that there are some issues with brandmauer. I can't use postgresql port because it's also busy and some ports are not working with other clients from the internet. May be, it is a problem with router, but I don't know for 100%. What do you think?
