Still in the Networking section, click the Network Rules tab then from the Tasks pane click the Create a Network Rule link.Ĭlick the Add button, then in the window that pops-up expand the Networks folder and select the DMZ network we created before. This will be a NAT relationship since our TMG server is connected directly to the internet. The first rule that we are going to create is between the DMZ network and the external one. It needs a NAT or route relationship with the other networks that TMG manages, and the next step is to create this relationship rules between the DMZ network and the other ones. Now just by creating the network it’s not going to do the job. The last step into making this rule functional is to hit the big Apply button so TMG synchronizes this configuration with it’s local database. Hit OK then Next to continue the wizard.Ĭlick Finish to create the perimeter network. Here, click the Add Adapter button and in the window that pops-up check the box next to your network card that belong to the DMZ/Perimeter network. In the second screen of the wizard select Perimeter and click Next. Type a name for the new network then click Next. The wizard that opens is not something new, and if you’ve been following along from the beginning, you can notice that is the same wizard as the one we used in the first section of the article. The first thing we need to do is to create the DMZ network, and for this open the TMG 2010 console, go to Networking and here click the Create a New Network link from the Tasks pane. Now, if you already have a TMG 2010 server running in your network, and I’m sure most of you have, creating a DMZ network involves a few more steps compared to the one mentioned above.

Right now, no traffic is allowed between the perimeter network and the other networks but I’m not going put here the step-by-step guide on how to create a firewall rule in TMG 2010, because I have an article exactly for that. The DMZ network is now created, but there is still one more thing to do that the wizard is not doing it, and that’s creating firewall policies. For this article however, we are going to choose Private since our TMG server is connected directly on the internet. We select Public if there is another firewall in front of the TMG 2010 server so we don’t do double NAT. Select it, then down at the bottom choose the type of network relationship you want the DMZ network to have with the rest of the networks. The last network interface is the one that needs to be assigned to the DMZ network. Here, select the adapter that is connected to your internet and once you’re done continue the wizard. A good practice is to name your adapters so you know which one is connected to which network.

Make sure you have all your network drivers and cards in order before launching the wizard.įrom the drop-down-box select the network adapter that is connected to your LAN network then click Next. If the option is grayed-out you either did not installed a third network card in the system or is not recognized by it.

If it’s a new install the deployment is easy by following the Network Setup Wizard.įrom the Network Template Section page all we have to do is select the 3-Leg perimeter option and click Next. Once we have these, there comes another question: is this a new TMG install or an already existing system? Configure a 3-Leg perimeter network with TMG 2010 from a fresh install In order to deploy a 3-Leg perimeter network with TMG 2010 we need to have a minimum of three network cards installed in the server one for every type of network (internal, external and DMZ). The second type is where one TMG server handles the security, the DMZ network, the internal and the external network and as the title says, this will be type of network discussed in this article. The first one is where our perimeter site sits between two TMG servers, one located in front of the internet and the other one in front of the internal network. With TMG 2010 we can achieve just this in a few easy steps, by either building a Back-to-Back DMZ or a 3-Leg DMZ. Creating forests and domains that will be exposed to the internet might be another reason to build a DMZ (or perimeter network), but whatever the reason might be, that network needs to be secured from outside threats.

You’ve been thinking on moving some internal services more closely to the internet to provide a better experience for your users, and you’ve heard that by creating a Demilitarized Zone (DMZ) will help you accomplish that, with security in place.
