With most routers, you can change the destination port, so this allows you to make camera 1 accessible on and camera 2 on. But if you forward this port to both camera’s it wouldn’t work. To access the camera from the internet you would need to connect to your public Ip Address, for example, 85.84.83.82 followed by the port number. So internally you can access camera 1 on Ip Address 192.168.0. Both camera only responds to a request over port 7080. Now let’s say you have two Unifi security camera’s that you want to access directly from over the internet. So we can send the traffic for our website that comes in over port 80 to our server that is listing on port 80 and the traffic for the PlayStation to the console itself. With Port Forwarding we can forward every port to the correct network device.
Now every application uses there own port number, for example, webservers are accessible over port 80 and an Unifi Security Camera can be accessed over port 7080. But to connect to the internet all devices share one public IP Address (in the examples above it’s 85.84.83.82) that is supplied by your ISP. Making multiple devices accessibleĮvery network device in your network has it’s own IP Address. The PlayStation will handle the data further. But our firewall has no idea who needs that, so it will drop the package.īy setup a port forwarding rule in our router, we can tell the router to forward all data package that is sent through port 3074 to forward it to our game console. If our friends try to join our game, a package is sent through port 3074. Our friends need to be able to connect to our PlayStation for that.īy default, the firewall in the router will block all unknown incoming traffic. Let’s say we want to host a game on our PlayStation for example. The router/modem has a built-in firewall.
This is commonly used for security camera’s, gaming, hosting a (web)server or making you NAS accessible from the internet. You only allow specific traffic (that comes through a port number) to travel into your network to the network device (or computer). With port forwarding, you can make a computer or other network device (the security camera for example) accessible from the internet. By opening and forwarding specific ports in your firewall you can safely run a web server or FTP server on your computer or host or join an online game. Otherwise, a hacker could gain easily access to your network.
PORTFORWARD PS4
With port forwarding, we can tell the router where to forward the packets that are meant for your PS4 for example.īy default, our firewall will block all incoming traffic, which is good. Port Forwarding is used to allow external devices (PlayStation network for example) to connect to your internal devices (PS4).
