I have a DLink Dfl600 and I have to tighten up our nertwork without going over the top.
We use Internet Acees, Email,Https sites x 2,skype,Remote Administrator.
What TCP Port numbers and especially UDP Port numbers should I allow in and out of these firewall boxes. We also use TMIS firewall software as well on all 14 pcs.
I need a fairly specific answer as I will be doing 4 of these in different problem area networks all with 2000 or 2003 Server.
