If you are experimenting with your wireless network, you may wonder how to close a router port. The best routers, after all, offer plenty of options when it comes to settings, including the ability to close and open router ports. Why would you close a router port and how would you do it? Keep reading to find out.
The main reason to close a router port is to address security and privacy vulnerabilities. If you just leave every port open at all times, even the unnecessary and unused ports, you are essentially putting yourself at risk for reason. Closing these ports will stop would-be hackers, so you won’t have to go online to learn what is a DNS address or how to change the DNS settings on a router and stop identity thieves.
In some cases, you may have to restart the router for these changes to be accepted.
This is a fairly straightforward process, akin to learning how to turn off 5GHz on a router. However, each router is different, so it varies according to make and model. With that in mind, we have tried to keep this guideline as universal as possible.
Your first step is to make sure your network is functioning properly and that you have a valid and strong Internet connection available to all wireless devices within range. Check to see that the router is plugged into the modem via Ethernet cable and that you use the network to connect to the Internet.
Now it is time to access a dedicated settings page or the admin panel. This process varies depending on the router, so check your instruction manual or hit up a quick web search for specific details on how to do this with your router. Be sure to set aside your network name, public IP address, default password, and any other relevant information for later.
In most cases, you can access the router’s settings page by inputting your router’s IP address in the address bar of a web browser. Otherwise, use dedicated firmware of a mobile app provided by the router’s manufacturer.
Once on the settings page, look for port options, otherwise called port forwarding options. Turn off whichever ports you desire and be sure to save your changes.
Router port 23 open, security risk?
This depends on your router and the specifics of your wireless network. Contact a community for developers for more information, or any related online community. Whichever current community you engage with should be able to help.
How to set up port forwarding on your router?
You can do this via command prompt or by following most of the aforementioned steps, clicking port forwarding instead of removing ports.
Where do I find a network vulnerability test feature?
Many routers include this feature via the admin panel, particularly newer routers.
STAT: UPnP and NAT-PMP are two different protocols that do the same thing – they let devices on your network poke holes in the router firewall. (source)
