Configuring Remote Desktop Gateway (RD Gateway) in Windows Server 2012 R2

If you have any feedback on our support, please contact tngfb microsoft. Thank you very much for your help so far. I think I've got the ports covered now.It allows authenticated and authorized remote users to securely connect to resources on an internal corporate or private network over the Internet.

RD Gateway server is exposed to the Internet an untrusted network and because of the reasons discussed in the Perimeter network sectioneither RD Gateway server is deployed in the perimeter network or RD Gateway server is deployed in the internal network with an ISA server in the perimeter network. A perimeter network also known as a DMZdemilitarized zoneor screened subnet is a small network that is set up separately from an organization's private network and the Internet.

Because of the increased potential of these hosts being compromised, they are placed into their own sub-network called a perimeter network in order to protect the rest of the network if an intruder were to succeed. Hosts in the perimeter network should not be able to establish communication directly with any other host in the internal network, though communication with other hosts in the perimeter network and to the external network is allowed.

This allows hosts in the perimeter network to provide services to both the internal and external network, while an intervening firewall controls the traffic between the perimeter network servers and the internal network clients. In a dual firewall perimeter network, a firewall is located on either side of the perimeter network. One firewall is connected to the external network, one firewall is connected to the internal network, and the perimeter network resides between the two firewalls.

This is a more secure approach because an attacker has to break both firewalls in order to get to the internal network. When there is no AD DS in the perimeter network, ideally the servers in the perimeter network should be in a workgroup, but the RD Gateway server has to be domain-joined because it has to authenticate and authorize corporate domain users and resources. The following diagram shows the traffic flow from the Internet to the perimeter network and from the perimeter network to the internal network in this deployment.

Figure 3: Traffic flow from Internet to perimeter network and from perimeter to Internal network. In this deployment, RD Gateway needs the ports to be opened on the internal firewall for the following purposes:. In this deployment, there is AD DS in the perimeter network which trusts the internal network forest to authenticate the internal network forest users in the perimeter forest domain. RD Gateway is joined to the perimeter network domain.

The trust between the perimeter network forest and the internal network forest is one-way, so configuring RD Gateway to use a central NPS server which is in the internal network is required in this deployment. Figure 4: Traffic flow from Internet to perimeter network and from perimeter to internal network. In this deployment, there is a read-only domain controller RODC in the perimeter network for the internal network forest.

Figure 5: Traffic flow from Internet to perimeter network and from perimeter to internal network. The internal firewall should allow all communication from the RD Gateway server to internal network resources. Firewall rules between the perimeter network RD Gateway and the internal network Domain Controller to authenticate the user:. Note: In Windows Server R2, RD Gateway can be configured to use non-native authentication methods through a custom authentication plug-in.

If RD Gateway is configured with a custom authentication plug-in, contact the vendor of the authentication plug-in to find out which firewall rules are required for RD Gateway authentication.

To know which protocol is needed to contact the CRL distribution point for a certificate, open the certificate and go to the Details tab and look at the CRL Distribution Points field. This scenario is possible in Windows Server or higher versions. This fixed WMI port needs to be opened on the firewall. This scenario is possible in Windows Server R2. Note: If there is an ISA server already deployed in the perimeter network of your organization, then RD Gateway server can be put in the internal network which reduces the number of ports that need to be opened on the internal firewall path from perimeter network to internal network to one.I've updated the port in RD gateway manager.

But then published apps didn't get RD gateway didn't get updated. Even after unpublish and re-publish. I am however able to manually connect desktop session if I don't use RD web published RDPs and specify my custom port.

Yeah, I tried the port triggering at first which worked fine for pulling up the RdWeb. But then the published apps still defaulted to So I abandoned the port triggering and just went for custom port throughout. The RDgateway itself worked well for port change.

It just left the published app without proper config. That powershell command above appears to have done the trick. But it did work prior if manually specifying RDgateway port It may have been a 4G tether glitch as I was testing off my laptop inbound from outside.

Thank you! Best Answer. Thanks for your reply. I really don't know why but published apps started working correctly. We found 4 helpful replies in similar discussions:. Fast Answers! There were a bunch of NAT rules I had to point to the new interface. Was this helpful? JitenSh Mar 01, This year I have configured 7 RG gateway's last year it was around RD Gateway. The configuration has been simplified in Windows Server and R2.

It offers the following benefits. It is recommended to always use certificates from a public Certificate Authority or an internal Certificate Authority. Self-signed certificates will show as untrusted as you will see in the example below. In the real world you would deploy using certificates from a CA your client trusts.

Select RD Gateway. Select the server name below and click the arrow to add it to the right hand column. In the below example the external clients would type rdpfarm. For an encrypted. Click Next. The information at the bottom lets us know the deployment was successful however a certificate needs to be configured. If you click "Configure certificate" you will be able to configure each roles needed certificate, however for informational.

Click Close. Next click on Tasks and click Edit Deployment Properties. From here we can edit many of the deployment settings. Our concern now is specifying a certificate. Since all roles are installed on a single server in this deployment, we need to be sure to use the same certificate.

Here it is possible to run in to some issues if using self-signed certificates. Since we do not have a purchased certificate or a CA of our own, we will click Create new certificate …. Pick the certificate name, which needs to match the external FQDN of the server. We have the option to store it. Not necessary here but a good idea if you back up. You must allow the certificate to be added to the destination clients Trusted stores. Click OK. Click Apply. As you can see I have applied the cert to both Roles here and it is Untrusted.

This once again is because it is. Click OK when finished. It would look more like what you see here.A Remote Desktop Gateway server is a Windows R2 server which typically is located in a corporate or private network. It acts as the gateway into which RDP connections from an external network connects through to access a Remote Desktop server Terminal Server located on the corporate or private network. The external network is usually the internet.

Remote Desktop Servers typically use port If you have more RD servers than you have internet IP addresses, you will have to start port forwarding other ports to the other RD Servers, i. This can be quite confusing for clients because they have to remember what port to connect to. Give them the name or private IP address of the Remote Desktop server that you want your client to connect to. As long as the RD Gateway can resolve the name, and the appropriate rights are given to the user credentials which your clients are using, they can connect to the Remote Desktop Server.

You can create groupings of servers and allow only certain Windows users or groups access to particular servers. I find buying an SSL certificate is best instead of using a self-signed one i. Make sure you install the latest RDP Client or at the very least version 6.

You can go into the Advanced section, and click on Settings in the Connect from Anywhere settings. See below screen shots as an example.
