I happen to be familiar with Unix firewalls but this Microsoft one is another - simply does not obey my rules. I need someone expert with it to help me out.
I have  a LAN in the 192.168.0.0 - 255.255.0.0 address range. ISA is running on SBS 23k. This PC has is multi-homed, with one public interface.

I need to do the following:

1. Allow pop3, pop3s, smtp, smtps, imap and imaps for everyone
2. Deny ALL Internet Access except to a few hosts. These exempted hosts have static IPs dished out via DHCP servers running either on the SBS or Cisco.

Now this is what I have attempted.

(a) Policy no. 1: Action = Deny; Protocols = All outbound traffic except selected (like above), From = Internal (with Exceptions), To = External
(b) Policy no. 2: Action = Allow; Protocols = Selected (FTP, HTTP, HTTPS) From = Internal; To = Selected Websites
....

Then I have the default Last Rule that DENYs everything.

What happens is that rule 1 stops the guys even from Accessing their e-mails and does NOT allow the PCs in the Exception list to access the Internet.

I am stumped.
