Ports 20/21

  Ramshackle 10:31 10 Aug 03

I wonder if anyone can help, I have just gone on to broadband and I have a Netgear Modem/Router
Model No.DG814 on XP.The problem I now have is that having had my ports probed! with ShieldsUp
I find that as opposed to my old dialup connection ports 20 and 21 are now on closed instead of stealth and can now be seen.I have Zone Alarm installed.
I'm not that computer literate and Steve Gibsons site is a little technical for my understanding.
Can you help me put them back to stealth mode.
