Many people complain of not being able to obtain access to the Internet from the ISA Server computer itself. This tutorial will show you an easy way to solve this common problem. 1. First, you must decide which protocols you need access to on the external network. Below is a table of the most popular ones:
Now, you will create an IP Packer Filter for each protocol that you will use on ISA Server machine. 2. Open the ISA Server Management console, navigate to [Server] expand Servers and Arrays, then expand [SERVER] and go to IP Packet Filters. Here you’ll create the IP Packet Filters to allow access to the Internet from ISA Server Machine itself. I will go over an example for SMTP. On the General tab you can enter a meaningful name for the filter and an optional description.
With this example and the table above you can create the filters necessary to allow the access to SMTP, POP3(S), IMAP, HTTP(S), SMTP(S), NNTP(S) and among others. TIP: To to the Policy Elements and then the Protocol Definitions node. You will find the definitions of the protocols. Always remember to invert of Inbound for Outbound.
