What is Port Forwarding vs Port Triggering – What are the Differences?
Port forwards are setup in your router. A summary of the steps to setup a port forward in your router are: Login to your router. Navigate to your routers port forwarding section, also frequently called virtual server. Create the port forward entries in your router. Test that your ports are forwarded correctly. Open Ports on Your Router. Opening a port on your router is the same thing as a creating a Port Forward. These open ports allow connections through your firewall to your home network. Having to create a port forward is common in gaming, VoIP configurations, and torrenting. The easiest way to forward a port is to use our Network Utilities suite.

Port forwarding or port mapping is the name given to a technique of forwarding data from a port on one node to another node. Port triggering is a dynamic form of port forwarding used when port forwarding needs to reach multiple local computers. Port triggering is used by network administrators to map a port or ports to one local computer.
In theory, sending data from device to device is a simple concept, but what happens when you want to access a service remotely? Your ability to connect with internal networked devices is restricted by a firewall that has been designed to keep out unwanted intruders.
To sidestep these concerns administrators use port forwarding and port triggering to allow end-users to connect. With port forwarding and port triggering data is forwarded to ports locally, remotely, and dynamically. The router acts as an intermediary that sends data back and forth between the networked devices in a way that external users can access.
Contents [ hide ]. Essentially data is intercepted and redirected from one computer to another. Port forwarding is used in scenarios where you want to access a networked device or service connected to the internet from a remote location.
However, on the whole, when data is transmitted from one location to another it is broken down into packets so that it can be easily transported. Each packet contains information that details things such as the final destination the packet is traveling to. These packets are sent between network devices through routers which act as intermediaries.
Routers are tasked with sending and routing packets to their final destination. To do this, the router looks at the information inside the packets. For example, the router uses the header of the packet to send it along to its final destination. Port forwarding changes this approach by having an application intercept packets once they are in transit.
The intercepting application takes on the role of the router and notes the packet header and destination before rewriting it. Once the information is rewritten the application then sends the packet to another destination that is different from the one originally listed. The first thing you need to set up port forwarding is a device using a static IP address.
A static IP address is essential because it ensures that you only need to enter the specific IP address once rather than every time the IP address is renewed. You can configure a static IP address from your computer or within the router. To select the IP address you want to click Add or Reserve so that packets are sent onwards.
Now log in to the router as an admin and find the port forwarding settings. These are generally titled Port Forwarding or Port Triggering but the name differs from router to router. Next, you need to type the port number or range that you want to forward. The process is slightly different for individual ports and port ranges:. Most applications will tell you the ports you need to open. To finish off, enable your new port forwarding rule by setting it to Enable or On. Port triggering is a dynamic form of the port forwarding model.
Generally, port triggering is used when the user needs to use port forwarding to reach multiple local computers. However, port triggering is also used when applications need to open incoming ports that are different from the outgoing port.
When using port triggering, the router is used to monitor traffic within the network. The user specifies a trigger port that sends outbound data. The router then logs the IP address of computers that have sent traffic to that port. The router then opens an incoming port or ports before forwarding the traffic to that location. It is important to note that port forwarding is dependent not just upon the user choosing a trigger port but also specifying which incoming ports you want to use.
This minimizes points of entry that cyber attackers can attempt to exploit. Here you will find port triggering options within or near port forwarding settings. Port forwarding is extremely important because it provides the user with a way to access LANs remotely through the internet. Port forwarding is important because most networks have a firewall that is used to block incoming ports. Firewalls keep these ports blocked to ensure that the network stays secure.
Without port forwarding, it would be harder for end-users to access services when offsite in a remote location. The router bridges the gap because it listens for traffic on specific ports and then forwards it to a resource once the user makes a request. At a basic level, port forwarding and port triggering are two different techniques for routing packets within a LAN. Each can be configured within the router to route traffic more efficiently.
However, while port forwarding and port triggering bear certain similarities they are different due to their use of open and closed ports. When using port forwarding a port on the router is left open continuously so that packets can be received easily. On the other hand, port triggering opens a port for a specified period of time. It is for this reason that port triggering is considered to be a dynamic extension to port forwarding.
Of the two techniques, port triggering is more secure because it minimizes the amount of time ports are left open.
Ports are vulnerable to cyber-attacks and port forwarding can be problematic because ports are left open continuously. In other words, port triggering is considered to be the superior technique in terms of security. UPnP is based on the PnP protocol that automatically connects devices with each other via peer-to-peer direct connections or a network.
Whenever a device is connected to the network it is automatically given an IP address and is provided with the details of other devices connected to the network. UPnP is important to port forwarding and port triggering as it is one of the technologies that underpin them. UpNp is used because it can accommodate ethernet, wifi, firewire, and Bluetooth connections.
As a protocol UPnP has a number of security issues that you need to bear in mind. One of the most significant is that there are a number of vulnerabilities within the code of UPnP that can be exploited by cyber attackers. Attackers can insert their own code to interfere with your network. This means that people can see your devices on the internet and attempt to gain access to private devices within your network.
As such, you need to be particularly vigilant when using port forwarding and UPnP. See also: LAN monitoring tools. As we discussed further above, port forwarding can be considered unsafe because it keeps ports open and thus vulnerable to external threats. The golden rule with port forwarding is that the method is as safe as the application where data has been forwarded to.
Making the decision to open a port should be made by considering the risks that you leave the network open to by opening the port. If you make the decision to open the port then you can minimize the risks by ensuring that the connected application is kept updated and patched.
Updating the application will help to decrease the risk of any vulnerabilities being exploited. Ultimately port forwarding should be used if the benefits to the application exceed the security risks that are possible by keeping ports open. As a result, VPN is used for many services as it provides a simple way for end-users to connect to remote services. There are a number of advantages that a VPN has over port forwarding particularly in terms of security. For instance, a VPN uses encryption and requires a password to be accessed.
However, a VPN is also easier to configure as well. Unlike port triggering and port forwarding, all ports and internal resources can be accessed with a VPN.
With port forwarding and port triggering, you need to create rules for devices that you want to use. Creating these configurations requires extra work from the administrator. VPN encryption may make users more secure but it also slows access to the service. Likewise, the sign-in process can take longer with a VPN as the user needs to log in to the VPN connection and then the internal resource each time.
Configuring a router to send packets to certain ports helps to automate packet flows so that remote users can interact with network services. Though port forwarding keeps ports open and raises more security risks, it is still widely used by enterprises today. Though this does help to increase security it is important not to fall into the trap of thinking that port forwarding is completely insecure. Port forwarding remains a viable option so long as you manage the connected application effectively.
With regular updates and patches, port forwarding is still relatively secure. It has a firewall and traffic management devices, such as load balancing and DDoS protection, to protect it. However, there will be a second firewall between the publicly accessible DMZ and the network used for office functions. Port forwarding involves network address translation NAT it maps private network IP addresses to unique public IP addresses for use on the internet. As you can see, DMZ is a network topology and port forwarding is an address management strategy.
In some instances, port forwarding is a bad idea. The incompatibility of private network addresses and the address space of the internet automatically creates a very strong defense against hacker attack — port forwarding weakens that defense.
However, businesses that need to allow incoming connections in order to operate will need to implement port forwarding. If that process is stopped, the port will be closed. It could be that the daemon has instructions within its code to stop once a transmission is received. It could also be that a network management tool has done a port sweep and closed all unnecessary ports — that is, killed non-essential services that expect to receive data on the network.
Ordinarily no. The device should start implementing the port forwarding instructions as soon as they are saved. Similarly, the removal of port forwarding instructions should be implemented as soon as the changes are saved. This site uses Akismet to reduce spam. Learn how your comment data is processed.
