Unless.......for example you can lock it all down to start with...blanket rule. Then allow ports as you come across them. Use netstat -a at cmd promt to see what port an app is trying to use and enable it as necessary, after a week or so, you will probably have come across most of the ports u need.
Ok, so maybe its a bit more complicated than that....but its not toooooo bad.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
