Forefront TMG 2. 01. Policy and Configuration Management Tips and Tricks. Introduction. There are a multitude of ways to manage the policy and configuration in Forefront Threat Management Gateway TMG 2.

During that time Ive also helped many organizations  small and large  design, implement, and maintain ISA and TMG. Needless to say Ive seen some well managed systems, and Ive seen my share of poorly managed ones. In this article I want to share with you some TMG policy and configuration management tips and tricks Ive encountered in my travels that will ultimately help make your TMG firewall easier to manage and perhaps even perform better. Custom Protocols. Forefront TMG includes many out of the box protocols to use when creating firewall access rules. There are times, however, when creating a custom protocol is required. An excellent example of this would be installing a third party management agent on the TMG firewall such as the Fastvue TMG Reporter arbiter which accepts inbound communication on TCP port 4. When creating the new custom protocol, include the protocol and port number along with a descriptive name in the Protocol definition name field, as shown here. Figure 1. Computer Objects.

This will make things much easier when you are looking at firewall policy rules and need to determine quickly if a specific IP address is allowed by policy. For example, here Im creating an access rule to allow the Fastvue TMG Reporter arbiter to accept communication from the TMG Reporter server in my lab with an IP address of 1. In the Name field Ive included the IP address of the system along with its fully qualified domain name. Figure 2. This same principle can also be applied to Address Range and Subnet network objects, as shown here Figure 3. There are a multitude of ways to manage the policy and configuration in Forefront Threat Management Gateway TMG 2010. Personally, I have been installing. There isnt a default Group Policy setting that will change this for you, but if you have a Windows 2008 or Higher Domain Controller you can deploy a registry. The client in the case of the mobile devices is the TMG server, or a similar solution. The certificate is what proves the identity of the mobile device, but TMG needs.

Figure 4. Access Rule Placement. When the Forefront TMG firewall has a lot of firewall policy rules, getting a newly created access rule in the right order can be challenging at times. Often TMG firewall administrators will create a rule that is intended to be included in an access policy group, only to find out that if the rule isnt created inside the group initially, the only way to add it to the group is to ungroup, reorder the rules, and create the group again. Very frustrating In addition, administrators sometimes inadvertently add a new access rule to a group when it shouldnt be included. Since it is not possible to drag and drop rules in to our out of access policy groups, here again your only option is to ungroup, reorder, and regroup again. Not exactly efficient0 Exchange 2013 Disk Space Requirement. The Exchange Team has changed their recommendation around the disk space required to install Exchange 2013, to be in line with. Today I continue my series of articles on Microsofts latest Forefront Threat Management Gateway TMG and will focus our efforts in publishing Windows 2008 R2. In this tutorial we will go over deploying a reverse proxy for Lync Server 2013. The original method for deploying a reverse proxy was to use Microsofts product. How to install Exchange Server 2010 Service Pack 3 to an existing environment. With a little planning and forethought it is possible to have the rule created pretty close to where we want it to be in the firewall policy. The trick here is, before creating an access rule, to highlight in the firewall policy exactly where you want the rule to be created. In this example I want an access rule to be placed first in the ordered list of rules, so I will highlight the first access rule in the list and then right click the Firewall Policy node in the navigation tree to create a new access rule. In this example youll notice that behind the new access rule context menu that the first access rule has been selected and is highlighted. Figure 5. Once complete, the new access rule will appear just above the rule I selected initially.

Additionally, if I wanted to add a rule to the end of the list, I would highlight the last Default Rule before creating the access rule. If I need to create a new rule and have it included in an existing access policy group I will first highlight a rule in that group prior to launching the access rule wizard. Access Policy Groups. One of the nice new features in Forefront TMG is the ability to create access policy groups. When you use the Getting Started Wizard to define a basic web access policy, TMG creates an access policy group to allow web access to all users and, if the option was selected, blocks access to common categories. Figure 7. Thankfully TMG administrators can create their own access policy groups as well. Begin by placing any existing access rules in consecutive order. It is not possible to group access rules that are not in order in the firewall policy. Next, select all of the rules to be included in the group, then right click on the selected rules and choose Create Group. Figure 8. Provide a descriptive name for the Policy group name and click OK. Figure 9. Once complete, you can reorder individual rules within the group and you can reorder the entire group within the firewall policy as required. As I mentioned earlier, adding and removing rules to or from an access policy group cannot be accomplished using drag and drop. As an alternative to ungrouping, reordering, and regrouping I will simply copy the rule I wish to remove from the group and paste it outside of the group in the firewall policy. Next I delete the original rule and then rename the rule I pasted earlier. Figure 1. 0Internal Network Properties. The Internal network properties configuration is an often overlooked area in my experience. In particular, the Forefront TMG Client tab is frequently configured improperly or has unnecessary options selected. By default, the option to Enable Forefront TMG Client support for this network is enabled. If you have not deployed the TMG firewall client, its a good idea to deselect this option. If you do plan to provide support for the TMG firewall client, its a good practice to specify the name of the TMG firewall or the array name if you have an enterprise cluster using a fully qualified domain name. Figure 1. 1Another troublesome area is the Client Computer Web Browser Configuration settings. These settings will configure the web browser of any client that has the TMG firewall client installed and enabled. By default, all of the options are selected Most environments will require only one of these settings. If youre planning to use WPAD, you can choose the option to Automatically detect settings and safely disable the other options. If youre not using WPAD and still want to take advantage of advanced web proxy features TMG offers, select the option to Use automatic configuration script. My preference is to use a custom URL and provide the fully qualified domain name. Figure 1. 2Lastly, if you want to direct web proxy clients to a specific proxy server or array, select the option to Use a Web proxy server and enter the fully qualified domain name of the proxy server or array. Figure 1. 3Configuration Change Tracking. Configuration Change Tracking is a great feature that first appeared in ISA Server 2. SP1, and is now included in Forefront TMG 2. Configuration Change Tracking records any changes made by the administrator, either programmatically or with the management console. When making changes using the management console, by default the administrator is prompted to enter a description of the change, like this Figure 1. Often I see TMG firewall administrators ignore this box. Ok, admittedly even I ignore this box too, but Im typically working in lab or demonstration environments so I have an excuse However, for production environments this dialog box should not be ignored.
