Port forwarding and VPNs are two common terms in networking that you might have heard of. People use port forwarding to speed up their internet connection. Although people refer to them as redundant technology, they can be pretty helpful.
Meanwhile, you can use them for a better gaming experience or remote access to devices. VPNs are typically used while port forwarding to perform certain functions. This article explains what port forwarding and VPNs are, how VPNs enable port forwarding, and how they work together.
What is Port Forwarding?
Each device connected to the router in a home has its IP address. The Network Address Translation (NAT) firewall inside the router hides these local IP addresses from the public. By implication, every device in the home will share a common IP address.
Further, the router’s NAT decides which local device will receive which packet data. This allows the router to protect the local IP address from public access. This explanation is essential to understand what port forwarding means.
How Does Port-Forwarding Work?
Port forwarding is a setting or configuration that allows the public to directly access the local IP address of each device connected to the home router. The move typically circumvents the router’s NATs, enabling each device to receive different packet data.
What is the Purpose of Port Forwarding?
Port forwarding comes in handy when setting up a direct connection between a remote device or your home network and an external device. Below are some areas of use of port forwarding:
- Watch monitors or security cams when you’re not around.
- Set up a remote connection to your home server.
- Create a direct gaming server connection.
- Connect to your home’s network IoT device.
- Give access to your public web servers to external servers.
- Allow remote computers to connect to your home desktop.
What is a VPN?
A Virtual Private Network (VPN) helps create a safe connection when using an open network. VPNs mask your virtual address and protect your internet activity. This makes it more complex for outside parties to monitor your internet activity and steal data. The connection is typically in real-time.
How Do VPNs Work?
A VPN redirects your IP address through a specially configured remote service controlled by the VPN host. By implication, the VPN becomes the source of information supplied to the web when you browse the internet.
As a result, neither your Internet Service Provider (ISP) nor other parties can see the sites you surf or the data you transmit and obtain online. A VPN acts as a filter that makes all of your data inaccurate. Even if somebody could get your data, it wouldn’t be helpful.
How Do Port Forwarding and VPNs Work Together?
Port forwarding offers faster internet connection access to home servers remotely. However, it opens your network to risk – this is where VPNs come in.
Also, combining port forwarding and VPNs helps establish a safe connection between a remote network and a computer. The router will forward incoming traffic on specific ports to the network you specify when port forwarding is active, allowing for a secure connection.
What are the Benefits of Using Port Forwarding and VPNs Together?
Below are the benefits of combining VPNs and port forwarding:
- It gives you access to apps and services blocked by your firewall
- It grants safe connection to remote networks
- It improves the safety of your secure connection by encrypting data transferred between the remote network and your computer.
How Do I Set Up Port Forwarding and VPNs on My Router?
Setting up this connection varies among different router manufacturers. However, many routers may follow similar settings to configure them. Check your router’s model to see how you can set up port forwarding on your particular router. They usually involve logging into your router, opening the port forwarding settings, and choosing a specific configuration setting.
Conclusion
Port forwarding is excellent as it helps you set up faster connections and access home servers remotely. However, it opens your network to risks since it’s been made public. Likewise, combining a VPN with your port-forwarded network can be pretty helpful. The VPN helps set up a safe connection while you have a smooth and fast internet connection from port forwarding. Enjoy!
