Router Port Forwarding

Port Forwarding, can be called port mapping. A word of definition of port forwarding is a way that bridge the communication Between one side and another side.

Normally, we surfy internet by using a router. That means our computer behind the router. Our compuer has a private ip address and the router has a public ip address. The requests of our computer will send to the router and the router will rely the requests to internet. This is how we surfy internet. Router is like a front door before your computer. But if internet users or applications want to access your computer, it will reach the router(front door) firstly. If there is no port opened for this request in your router. Your router don`t know how to deal with this, So your router will refuse the request directly. This will result internet users or applications can not access your computer. Port forwarding is the right way to resolve this. What you need to do is just add a port forwarding entry into your router, then your router will know how to forward the request from internet users or applications to your computer that behind the router.

Port Triggering is an option of router. Basically, port triggering and port forwarding are the same. They all open a port on your router and when there is connection or data from internet, your router will forward the connection or data to your local computer that behind router. The difference between port triggering and port forwarding is, when you use port forwarding function of your router, your router will always open the port no matter you are using it or not and the internal address be forwarded is Static, if you want to change the address that you want to forward, you must edit the port forwarding entry in your router. Comparing with port forwading, port triggering is a Little more secure and it is dynamic. When your application need to open a port in your router, the port triggering function integrated with our Router Port Forwarding software will do this for you.
