(2) Third-party firewall s

If you are using a 'third party' firewall (Symantec, Kaspersky, Mcafee, Avast, AVG) then you will need to refer to your particular firewall's documentation for how to do this. The easiest option is probably just to search (using a search engine, such as Google) for 'How do I open a port in X' with "X" being the name of your firewall software.
