Hi,<br />
<br />
By defaul ISA server creates Deny all rule so all the traffic is denied.<br />
<br />
Now if you need to allow some traffic you need to create rules accordingly. For achiving your goal create a rule to allow for POP3 from internal to External for all the users.<br />
<br />
If you wan to allow specific users or grop to go to Internet create a rule to allow HTTP and HTTPS from Interneal To External for selected users or groups..<br />
<br />
Hope this helps<br />

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.

Microsoft Forefront, formerly known as Internet Security and Acceleration Server (ISA Server), is a network router, firewall, antivirus program, VPN server and web cache that runs on Windows servers.
