I would like to know which port is safe to be opened by ISP.
For given ports, it has been used for connections by ISP, when I use following commands, it shows connections existed with given ports
How do I know which ports must be opened for accessing internet?
Would it be possible to close any unnecessary ports if it does not required to be opened?
Does anyone have any suggestions?
Thanks you very much for any suggestions
