In-Reply-To: <3DCD2368.5050203 () compulink gr> Hi, It depends totally on the application you are using. Both TCP and UDP are IP protocol types, and there are others like IP proto 47 (used by PPTP) etc. which you would need to open in case the application needs it. As always, do not open any additional ports / protocols unless they are used by the application at hand. For a more comprehensive distinction between UDP and TCP, I would suggest any standard text on Networks (Tanenbaum etc.) Regards, Arvind Shyamsundar Brainbench MVP for Internet Security http://www.brainbench.com
