Set up a Router Firewall

This article talks about how to set up a router firewall or configure your router for activating the firewall. We also take a look at what all ports do you need for regular working.

Open Router Firewall Configuration & Settings Page

Before you can turn on the router firewall, you will need the IP address to get to the configuration page. To get the address, open the RUN dialog by pressing Windows Key + R. Type CMD and press Enter.

In the command window, type IPCONFIG /ALL and press Enter. Make a note of IP address provided next to Gateway. You will have to type that address (in the form of numbers, including the dots) into a browser address bar to open the router configuration page. That number would work in most cases. If it doesn’t work, please contact router support for the address.

Configure Router Firewall

This is simply turning the firewall on/off. If you’ve installed Windows, chances are the operating system has already set up your router during installation. You can set it up manually too, using a browser of your preference.

To set up a router firewall:

1 Access the router homepage by typing router IP address in a browser (The one you noted down in the above section; example: 192.168.1.1)

2 Check for Firewall option on the router homepage. This option can be grouped under different names such as Advanced Settings

3 If the Firewall is deactivated or not enabled, click to select and activate it

Important Ports On A Computer/Network

The router configuration page differs across different manufacturers. However, the option to open or block a set of ports should be present on all. You should look for “port forwarding” to block unauthorized access requests in a way that you do not block your important Internet connections. The following is a list of ports you need to keep open. If on Windows, you need not worry as it takes care of the port restrictions.

PORT NUMBER 80 allows for Internet Access (HTTP)

Port Number 443 allows for Secure Internet Access (HTTPS)

Port Number 25 is the port through which you can access emails (SMTP)

Keeping open the above ports is sufficient for normal browsing and email work. Additional ports may be required depending upon your special software needs. In that cases, the software itself will take care of opening the required port.
