Hi I have recently installed a MS Small Business Server 2000 server for my business which includes Microsoft ISA server which provides internet access and firewall etc. The problem I have is that a piece of software I use requires the use of ports 6641 and 6642 for updating over the internet and the ISA server will not allow me access. How can I configure it to open up these ports and allow the program to communicate with the internet? If anyone knows or has any pointers it would be a great help. Thanks Russ
