Hi, Maybe someone can help. I've got a web server published behind ISA server with no problem. Now running on the published web server is Seagates Crystal Reports (used for running reports from web browsers). I know that Crystal Reports listens on TCP port 6401 and 6403. My question is: What type of Packet Filter should I create to allow external web users (through ISA) to get reports to run successfully from internal web server. I'm not sure what specifics should be used in the packet filters knowing that Crystal listens on TCP port 6401 and 6403. Can any of you packet filter experts help out?
