I inherited an ISA 2000 server and for the most part I have been able to figure out so far but now I have a problem that I don't know how to solve it.
This ISA 2000 server has two network adapter. One that connects to the internet and another that connect to a external private network. In the one to connect to the external private network, I need to open some ports in order to communicate to a new application. I have been trying create some packet filtering but it has not worked so far.
The application opens from the computer that has the ISA server installed, but If I try to run the application from another computer using a proxy server (Which is the ISA server) I 'm not able to open it.
Thanks for your help
