That's the problem,I tried to make the exception in the firewall but nothing worked. And for the porting stuff I am never done such a thing and I don't have an idea how.
Well I looked up on google before even making this thread and I haven't found a certain way to allow it through avast 2017's firewall.Most of the sites I found just talk about white listing files and websites or older versions of avast. But if you found the website that tells how to do it I will be really thankful :)
