2802 - Enabling the DNS Forwarding Proxy Service
Scenario
You're tasked with enabling the DNS Forwarding Proxy (DFP) service on your organization's NIOS-X (formerly known as BloxOne Hosts) servers, oph1.techblue.net and oph2.techblue.net. You will connect these servers to the service instances DFP-OPH1 and DFP-OPH2 in the Infoblox Portal.
Estimated Completion Time
10 to 15 minutes
Prerequisites
Administrative access to the Infoblox Portal
Tasks
Enable DNS Forwarding Proxies (DFP) on both NIOS-X Servers.
Verify the NIOS-X servers and DFP services are functional.
Task 1: Enabling DNS Forwarding Proxies (DFP) on both NIOS-X Servers
In the Infoblox Portal, create two DFP Instances named DFP-OPH1 and DFP-OPH2 and connect them to the NIOS-X servers oph1.techblue.net and oph2.techblue.net.
Task 2: Verifying DNS Forwarding Proxies (DFP) Services Are Working
In testing-linux in a terminal window use the command sudo set-network-static-bloxone
to set a static IP address for the VM. You might get a red error message "Failed to reload network settings: No such file or directory". If you do, please re-enter the command.
In the lab environment, provision the VM testing-linux with a static IP address (with the command
sudo set-network-static-bloxone
) to reach the NIOS-X servers.From the VM testing-linux, perform DNS lookups using the NIOS-X servers (10.100.0.110 and 10.200.0.110) to make sure the DNS Forwarding Proxie services are working.
Solutions
Task 1 Solution: Enabling DNS Forwarding Proxies (DFP) on both NIOS-X Servers
Log into your lab’s VM jump-desktop.
While logged in to jump-desktop, use your Education Infoblox Portal Credentials to log into the Infoblox Portal.
Navigate to Configure → Service Deployment → Protocol Services.
Click Create Service and choose DNS Forwarding Proxy from the list.
Enter DFP-OPH1 for the name.
Click Select Server and choose oph1.techblue.net from the list
Click Finish and then Save & Close.
Repeat steps 3 and 4 to create a second DFP service.
Enter DFP-OPH2 for the name.
select oph2.techblue.net as the server.
Click Finish then Save & Close.
Task 2 Solution: Verifying DNS Forwarding Proxies (DFP) Services Are Working
Log in to the VM testing-linux in your lab environment with the credentials
training / infoblox
.Open a terminal window and enter the command
sudo set-network-static-bloxone
This command sets a static IP address for the testing-linux VM so it can reach the NIOS-X servers.NOTE: You might get a red error message "Failed to reload network settings: No such file or directory". If so, please re-enter the command.
Using the command dig against oph1.techblue.net (10.100.0.110) and. oph2.techblue.net (10.200.0.110), resolve the domains
www.infoblox.com
andwww.google.com
. Both domains should be resolved with a NOERROR response code. The commands are:dig @10.100.0.110 www.infoblox.com.
dig @10.100.0.110 www.google.com.
dig @10.200.0.110 www.infoblox.com.
dig @10.200.0.110 www.google.com.
