A network diagram is a graphical tool that illustrates the flow of information through a network and shows how devices communicate with each other. In the below article, we discuss the usage of a DMZ Network Diagram and understand the difference between a DMZ Network and a Firewall.

The Demilitarized Zone (DMZ) is a feature that allows only one local user to get exposed to the internet for special purposes while maintaining that all other setups within that network are well secured from any outside internet. In simpler words, any service provided to users on the public internet should be placed in the DMZ network.

Keep reading to learn more about the DMZ Network Diagram and how to create one using EdrawMax Online.

1. What is a DMZ Network Diagram?

As stated above, a DMZ Network is a perimeter network that protects and adds an extra layer of security to an organization's internal local-area network from untrusted traffic. As shown in the DMZ Network Diagram below, the primary goal of having a DMZ network is to protect and monitor network nodes installed outside the internal network.

Before you go ahead and learn how to create a DMZ Network Diagram, you should first understand when to use a router DMZ host.

- Use DMZ Host as a last measure when resolving issues
- Use DMZ Host for applications that require the random port to be opened
- Use DMZ Host when you need to host a home-based web server
- Use DMZ Host for gaming consoles.

Work on your research
Do not get confused over DMZ and Firewall. However, learn if the DMZ diagram requires a Firewall as well. In that case, ensure that the Firewall diagram is properly configured.

Export & Share

Once your DMZ Network Diagram is completed, you can share it amongst your colleagues or clients using the easy export and share option. You can export the Network Diagram in multiple formats, like Graphics, JPEG, PDF, or HTML. Also, you can share the designs on different social media platforms, like Facebook, Twitter, LinkedIn, or Line.

Important Tips

People tend to get confused between a DMZ network and a Firewall. As the diagram below shows, a DMZ is a portion of the network carved off and isolated from the rest. At the same time, a firewall is an appliance that creates the said isolation. The job of a firewall is to restrict the traffic from both the internet and the DMZ. Do understand the difference correctly before starting to create the DMZ Network Diagram.

Conclusion

As we saw from the DMZ Network Diagram, if your router offers a real DMZ, then the rest of the network would be safe even if your system is compromised. In such cases, creating a DMZ Network Diagram with proper annotation is mandatory. Use EdrawMax Online to create a similar-looking DMZ Network Diagram that provides all the network symbols and templates that ease down your efforts in creating the network diagram for your projects.
