- Understanding ISA 2004 Monitoring (Part 1) - The Dashboard and Beyond
- Date - Feb 02, 2006
- Many organizations have the basic requirement of being proactive, and have taken the measurement approach when identifying if the IT/IS investment in their information technology assets are being maximized. The only true way of measuring and managing this resource is by monitoring the resource closely and reporting on the resource on a continuous basis. Security assets that are critical to the business are often installed and forgotten and this is why it is recommended that a strong understanding of the monitoring process of ISA 2004 is fundamental to its management.
- How to work around an issue with VPN clients and split DNS
- Date - Jan 26, 2006
- In the past I have read a lot about VPN users having problems accessing internal resources which are also published on the same ISA server.

Now, I would like to share a nice workaround to that problem.
- Creating a Parallel ISA Firewall Configuration in a Netscreen DMZ
- Date - Jan 17, 2006
- Over the years there have been a number of questions about how to configure the ISA firewall in a “hardware” firewall’s “DMZ”. I have to admit that this question never made much sense to me, since I couldn’t figure out why the fledgling ISA firewall admin would want to create such a configuration. It seemed to be a simple affair to place the ISA firewall either in parallel or in a back to back configuration with the “hardware” firewall in front of the ISA firewall, allowing the ISA firewall to provide its superior level of protection nearest to the protected resources.

- Bypassing the Firewall Client using Locallat.txt File
- Date - Nov 03, 2005
- As we all know, ISA Server 2004 is a firewall and its function is to block all unnecessary traffic. But sometimes it is also necessary to bypass the traffic without going through the ISA Server. The following section will explain the options available on ISA Server 2004 and on the client side to achieve this.
- How to Record URL and User Information in ISA 2004 Firewall Logs and Reports
- Date - Jul 05, 2005
- One of the most common questions I see on the ISAServer.org Web boards and mailing list is how to get user and URL information in the ISA firewall’s logs and reports. The ISA firewall creates reports using ISA log summaries. The log summaries are derived from the ISA firewall’s Web Proxy filter and Firewall service logs. If you want to see user information and URLs (instead of IP addresses) in the reports, you’ve got to get that information into the logs first.
- Enabling DHCP Relay for DMZ Segments
- Date - Jun 21, 2005
- In an earlier article I discussed how you can configure the DHCP Relay Agent on the ISA firewall to deliver DHCP options to VPN clients. The VPN client situation is somewhat unique, in that the RRAS server obtains IP addresses on behalf of the VPN clients, and then when the VPN clients connect to the ISA firewall’s VPN server component, the RRAS service provides the VPN clients with an IP address. The RRAS service never sends the VPN client DHCP options. That is why you need a DHCP Relay Agent on the ISA firewall. The DHCP Relay Agent forwards the DHCP messages to a DHCP server on the corporate network.
- Configuring the ISA Firewall to Support TZO Dynamic DNS Services
- Date - Jun 14, 2005
- Dynamic DNS (DDNS) services enable users with dynamic IP addresses to register domain names users on the Internet can use to reach published resources. These DDNS services are a tremendous boon to small and home business users who would like to take the reins and run their own Internet accessible services.

- Supporting ISA Firewall Networks Protecting Illegal Top-level Domains: You Need a Split DNS!
- Date - May 31, 2005
- Of all the issues in ISA firewall networking, the one that most commonly gets people hot under the collar is that of the split DNS. I’ve never been able to figure out why barriers go up for a lot of folks when you begin to talk about a split DNS. Maybe it’s because they believe they need to rename their internal network domains, or that they think there is an adverse security impact, or maybe its just because DNS is so difficult to understand in the first place, that the idea of further complicating the issue puts them over the edge.
- Playing Well with Others: Configuring the ISA Firewall on a PIX DMZ for Secure Remote Access to OWA and other Exchange Services
- Date - May 24, 2005
- One issue that I rarely had to deal with before ISA Server 2004 came out was whether an organization needed to remove its current PIX firewall infrastructure to securely support ISA Server 2000 remote access scenarios to Exchange Server. Unlike the new ISA firewall, organizations considered the ISA Server 2000 to be primarily a Web proxy server akin to Proxy Server 2.0. Since there was this perception of ISA Server 2000 being only a proxy server, there was never a question on whether the PIX should stay where it was. The questions were more along the lines of where best to put ISA Server 2000 behind the PIX.
- Enabling DHCP Relay for ISA Firewall VPN Clients
- Date - May 17, 2005
- We all know that the ISA firewall provides unparalleled firewall protection when the ISA firewall is placed on the Internet edge, DMZ, or on one of the perimeters of you internal network security zones. In addition to the ISA firewall’s state of the art stateful packet and application layer inspection mechanisms, the ISA firewall is a one of a kind VPN server and VPN gateway that allows both remote access and VPN gateway connections to the ISA firewall. Of all the VPN devices I’ve ever worked with (and I’ve worked with a lot of them), the ISA firewall’s VPN is the easiest to configure and the most secure I’ve ever seen.
- Editing the ISA Server 2004 System Policy (Part 2)

- Step-by-Step: Publishing a Single Exchange 2003 OWA with ISA 2004 Firewall Forms Based Authentication
- Date - Jul 24, 2004
- I decided to take the DIY approach for setting ISA firewall to securely publish Exchange 2003 Outlook Web Access using forms-based authentication and SSL bridging to provide a higher level of security in web mail access. I believe this step-by-step article will take out some of the guess work that I went through when checking the configuration.
- Renaming ISA Server 2000 and ISA Server 2004 Firewalls
- Date - Jun 14, 2004
- A common ISA firewall administration task is renaming the firewall. The firewall may need to be renamed because you are moving it from one location to another, or the machine was in a test network and now needs to be moved to a production network, or because the machine is using a name that you want to assign to another machine. Whatever the reason, many ISA firewall administrators want and need to rename the ISA firewall. This article shows you how to rename both ISA 2000 and ISA 2004 firewalls.
- ISA Server 2004: Supporting Both Basic and Forms-based Authentication with a Single External IP Address and Web Listener (v1.1)
- Date - Mar 11, 2004
- one problem with the OWA forms-based authentication mechanism as implemented in ISA Server 2004 is that forms-based authentication and other forms of authentication are mutually exclusive on the same listener. This means if you enable forms-based authentication on a Web listener accepting incoming Web connections, then no other authentication method can be used. This is problematic for users who have only a single IP address bound to the external interface of the ISA Server 2004 firewall and need to publish both the OWA and Exchange Mobile Access sites (such as OMA, Active-Sync and Exchange RPC/HTTP. This article provides you with a powerful workaround.
- Publishing FTP Sites with an Alternate Port using ISA Server 2004 Firewalls
- Date - Feb 19, 2004
- One of the most common requests seen on the Web boards here at www.isaserver.org is for instructions on how to publish an FTP site on an alternate port. There are a number of reasons why someone might want to publish an FTP site on an alternate port. Some ISA admins feel that they’ll benefit from a measure of security through obscurity. Other ISA admins, believe it or not, actually want to publish an FTP site on an alternate port in order to violate their ISP’s Terms of Service policy. Regardless of the reason, this article will show you how to do it with ISA 2004 firewalls.

- Manually installing the ISA firewall client.
- Date - Nov 28, 2001
- The main reason that the firewall client is beneficial to an organization is that user or group access control can be used. Secure NAT does not allow this. The firewall logging is also more detailed, and you are also able to see which users are visiting which internet resources. The downfalls of the firewall client are that the software has to be installed on each machine that needs to become a firewall client and that the software is only Microsoft 9X and above compliant. Firewall clients only support TCP & UDP protocols.
- Configuring the SMTP Message Screener.
- Date - Nov 28, 2001

- Date - Oct 18, 2001
- When ISA Server was in beta testing, and shortly after its release, there were a lot of questions about how the H.323 Gatekeeper worked. In the last several months I haven’t noticed many questions about the Gatekeeper. Perhaps everyone has got the Gatekeeper all figured out and there’s no reason to ask questions. Or maybe the Gatekeeper is so impossible to figure out that everyone has given up! Hopefully it’s the former and not the latter because the H.323 Gatekeeper is really cool and promises to find a larger place now that gratuitous travel can be a dangerous adventure.

During the contract period, hundreds of your company's employees will access a special Web site created by your partner company. The Web site contains a lot of documentation and other information that your employees will use during the contract period. To make the best use of Web site and to speed that Web site's information along to your employees, you make sure your cache policy is working in the most effective way, and as users begin accessing the Web site, your ISA Server arrays begin caching the data from the special Web site in order to serve it to your users more quickly.
- Configuring RAM Caching.
- Date - Oct 02, 2001
- One of the main features of ISA Server is its ability to cache Web pages so that clients can be served from the cache instead of Internet. In order words, when a client requests a Web page, ISA Server, according to the configured rules, retrieves that page from the Web, caches it, and returns the page to the client. When another client requests the same page, it can now be directly returned to the client from the cache, according to the TTL value. This caching function accounts for ISA's "acceleration feature. After all, ISA Server can more quickly serve a client from its disk cache than from the Internet.

- Configuring the HTTP Redirector.
- Date - Jun 27, 2001
- As you are well aware, ISA Server can function as a caching server, a firewall, or in integrated mode where both firewall functionality and caching functionality are used together. In such cases, the ISA firewall and the Web Proxy Service are designed to function together so that all Web requests from firewall and SecureNAT clients are passed to the Web Proxy Service. This feature enables firewall and SecureNAT client to retrieve Web data that is cached on the ISA Server without any direct browser configuration. An application filter, called the HTTP Redirector, handles this feature.
