Abrir firewall

i think i can help

I have worked with firewall and Linux for more than 10 years. I can check what ports you need to open to get your service running. All you need to do is make a description of what are you trying to do and give me access to your system and redo your trying, so I can collect out the network activity and see what is preventing your connection to work. thank you.
