Hi
I am new in this group (from Norway)
Do you have any tips for which ports I should close to held my network
clean for intruders ? I've closed port 1214 and 6881 to 6889 . Anyone else
I should close ?

Chris

You're thinking about it backwards.  Close EVERYTHING, then make a list of the

It depends on what services you provide to the outside world as to which ports 
you will open.
