I'm trying to set up our web server on an NT 4.0 sp6 I know that I only need some of the ports of the "permit all" or "permit only" settings. Does anyone know which ones? we are only going to use our server for information to our clients, and form get through asp pages, we have frontpage extensions installed. We might put secure pages SSL in the future. I don't want to start setting up numbers and find out that a client can't get to our site, or that they can't upload a form or something. Any help would be appreciated. Thank you.
 
As far as what you mentioned you can block all UDP ports, ASP and SSL run over TCP using the HTTP protocol. UDP is unreliable, it is mostly used for computer broadcasts, video games, name resolution. You may also want to post this in the Data Transmission->TCP/IP forum.
 
For web pages, block all ports, all protocols except TCP port 80. When you add SSL, open up TCP port 443. (although, it might also be 433 -- my CRS is acting up again :) )
