Router DMZ Settings
Protection to the computers is a very important thing that should be done to save the information available in the system. In order to make the protection very strong, many settings are being installed in the routers of the network. Especially in order to protect a particular LAN from Internet abuse, such security settings are needed. Many methods like setting password for accessing the network router and other authentications are used for protecting network from strangers. But these methods are volatile and can be easily known by any stranger easily. If a network is not protected by implementing some security settings then the entire network may get affected by the external intrusion. In some cases, some confidential information of a network can be easily exposed through the website of the organization. In order to solve all these problems, there is a set-up called DMZ which helps in the network to be safeguarded form external threats. By implementing the router DMZ settings, it is easy to protect the most important data of a network.

What is DMZ
DMZ can be expanded as Demilitarized Zone, this is a simple sub-network which might either be physical or logical type. This layer enables one part of the network or one system of the network to be accessed by external users like Internet users. Other systems in the network are not allowed to communicate with the external users. This is like an extra layer of protection to computers in the network. This layer allows only particular system’s data to be accessed by the external users. This layer is like the front end of the software. That is only the interface is provided to the external users. But the internal data that process the inputs of the users are secured in another inner layer.
Services of DMZ
The most important place where router DMZ settings should be installed is web servers. The database server must be accessed by the web servers by some methods. If this access is not moderated, the data might be exposed to the online users by tacking the path of the files. Only the services that are to be rendered to the external users or web users can be placed in DMZ for blocking the users to have access to the data in the internal database of a web server. Similarly DMZ is very helpful for protecting e-mail servers and proxy servers. In case any external hacker tries to steal the information available on public systems, it does not mean that the entire LAN is going to be hacked. DMZ makes it very difficult for any external user to hack the information inside the LAN. In the public systems, the sensitive information is not usually shared. Just the application that can be used by the external users can be accessed.
Some simple processes are to be carried out for enabling or disabling DMZ on a router. For changing the settings, get access to the utility page by entering the IP address of the system in the address bar of the web browser that you are using. This utility is generally the control panel of the modem settings. This enables you to change the password and some important information in the internet connection. In this utility page, just find the tab where DMZ settings are mentioned and give the option that can turn on or turn off the DMZ settings on the router that you are using for connecting your computer to internet. After doing the changes just give the option for saving the settings and exit the utility page.
