Router Firewall


What is a Router Firewall?
A router firewall is a physical device that controls the incoming and outgoing traffic through an Internet connection. This is a spec that you wont find for most of routers I did spend months searching for that, and had to buy one to find out For those to think "what is this forwarding ports important for? You can have the router forward some traffic by setting up port-forwarding or putting a computer in a DMZ demilitarized zone , where all incoming traffic is forwarded to it.

How Software Firewalls Work

Once the connection passes through the router firewall, it effectively blocks anyone from gaining access without the proper credentials.

It is up to an administrator at that point to decide who gains access to the Internet and who doesn't. Over 90 percent of the world's online population connects through a router firewall daily, many of them without even realizing it. Even if they do not own the device personally, there's an excellent chance that they connect to the Internet at work, from a wireless fidelity WiFi hotspot, or through a telephone network that has a router firewall at the business end.

Internet providers use this technology to ensure that their customers have unlimited access to the web while blocking out all other requests for usage, and the entire process happens in milliseconds. Homeowners and businesses normally have to set up a router firewall one time and no further maintenance is necessary unless they wish to grant access to additional users. This additional security step is taken to ensure that only authorized users are permitted access to the network, and it also allows for any forced intrusions to be monitored in real time.

Hackers are known for trying to find vulnerabilities within router firewalls, but if they are set up correctly, they are normally very secure. In fact, many router firewalls can completely mask a network from being visible in cyberspace, so criminals do not even know that the entity is there.
