By the end of this guide, you will have gained the knowledge and confidence needed to set up port forwarding on your AT&T router. So, let’s jump in and start adding that front server!
Understand the Basics of Port Forwarding
Port forwarding is a critical process that allows you to open specific ports on your router’s firewall and forward incoming traffic to a specific device on your network, like a server. In simple terms, port forwarding enables access to a specific device or service behind your router’s firewall.
One of the most important aspects of port forwarding is understanding the difference between TCP and UDP protocols. Transmission Control Protocol (TCP) is a reliable protocol that ensures packets are delivered to their intended destination. User Datagram Protocol (UDP) is a connectionless protocol that does not guarantee packet delivery.
Before you start port forwarding, you need to know which port or ports you want to forward. Typically, this information can be found in the documentation for the device or service you are trying to access. Once you know which port to forward, you can start the process of setting up port forwarding on your router.
It is important to note that port forwarding can make your network vulnerable to outside attacks, especially if not configured correctly. Always ensure that your router firmware is up to date, and that you use strong passwords and other security measures to protect your network.
In addition, you should also consider setting up a Virtual Private Network (VPN) to protect your network and devices. A VPN encrypts your network traffic and provides an additional layer of security, making it harder for attackers to exploit any potential vulnerabilities in your network.
By understanding the basics of port forwarding and taking appropriate security measures, you can safely and securely open ports on your router’s firewall and allow incoming traffic to reach specific devices or services on your network.
What is Port Forwarding?
Port forwarding is a process that allows external devices to communicate with devices on a private network. By forwarding incoming network traffic to a specific device, you can ensure that requests made to your network are correctly routed to the intended device.
In order to understand port forwarding, it is important to first understand how devices communicate on a network. Every device on a network is assigned an IP address, which serves as a unique identifier for that device. When one device wants to communicate with another device, it sends a message to the target device’s IP address.
However, if the target device is located on a private network behind a router, the message will be sent to the router’s IP address instead of the target device’s IP address. This is where port forwarding comes in – by configuring the router to forward incoming traffic on a specific port to the target device’s IP address, the router can correctly route the message to the intended device.
Without port forwarding, external devices attempting to communicate with devices on a private network would be unable to establish a connection, resulting in network errors and communication issues.
Overall, port forwarding is an essential tool for enabling communication between devices on private networks and external devices on the internet. By forwarding incoming traffic on specific ports to the correct device, you can ensure that your network is configured to allow communication with the devices that need it most.
Why Do You Need Port Forwarding?
Improved Connectivity: Port forwarding enables you to connect to services running on your local network from the internet, giving you a more seamless experience.
Remote Access: With port forwarding, you can access your home or office computer from anywhere in the world, making it an essential tool for remote workers.
Better Gaming: Port forwarding can improve your gaming experience by allowing you to connect directly to game servers, reducing lag and improving response times.
Secure File Sharing: By configuring port forwarding, you can safely share files and documents with others over the internet without compromising the security of your network.
Efficient Resource Utilization: With port forwarding, you can optimize the use of network resources, as traffic is directed to the appropriate device, improving the overall network performance.
How Does Port Forwarding Work?
When you request a web page or any other internet resource, the request is sent to a specific port on the server hosting that resource. Port forwarding allows you to direct incoming traffic from a specific port to a specific device on your network, like a server, game console or security camera.
To put it simply, when someone tries to connect to your device using a specific port, your router will forward that request to the designated device, enabling the user to access the resource they were seeking.
The process works by creating a rule on your router that tells it which device should receive the incoming traffic. Once the rule is created, any requests that match the rule will be forwarded to the designated device, allowing the device to respond to the request.
Port forwarding is especially useful when you want to host a server on your network, as it allows you to receive incoming requests from users outside your network. It also allows you to control access to specific devices on your network, by limiting access to specific ports.
However, it is important to note that port forwarding can also pose security risks if not properly configured. This is because it exposes your devices to the internet, making them more vulnerable to attacks.
Access Your Router’s Settings
Step 1: Open a web browser and enter your router’s IP address in the address bar. The IP address is usually printed on a sticker on the bottom of your router or in the user manual.
Step 2: Enter your router’s username and password to access the settings. If you don’t know your login credentials, try using the default username and password, which is often printed on the same sticker as the IP address.
Step 3: Once you’re logged in, navigate to the port forwarding section of your router’s settings. This may be labeled differently depending on the router, but it’s often found under the “Advanced” or “Security” tab.
Step 4: Make sure that port forwarding is enabled on your router. If it’s not, you may need to enable it before creating a new port forwarding rule.
Step 5: Take note of your router’s IP address, as you’ll need it when creating a new port forwarding rule.

Step 1: Choose the device – Select the device that you want to forward ports to. This could be a computer, gaming console, or any other device on your network that requires an open port.
Step 2: Enter the port range – Determine which port or range of ports you want to forward. Remember to check if the application or service requires a specific port number or range.
Step 3: Choose the protocol – Select the protocol that you want to forward the port for, such as TCP, UDP, or both.
Step 4: Save the rule – Once you have entered all the necessary information, save the new rule. Your router will now forward incoming traffic on the specified port(s) to the designated device on your network.
Select the Protocol
When creating a port forwarding rule, you must select the protocol that will be used for the connection. The two most common protocols are TCP and UDP. TCP is used for most applications, including web browsing and email, while UDP is used for streaming media and online gaming.
Some routers also support other protocols such as FTP, SSH, and ICMP. FTP is used for file transfers, SSH is used for secure remote access, and ICMP is used for network diagnostics.
When selecting a protocol, it is important to choose the correct one for your application. Using the wrong protocol can cause connection issues or prevent the application from working properly.
Enter the Port Number and IP Address
Once you have selected the protocol, the next step is to enter the port number and IP address for the device you want to forward the port to. The port number is the specific numerical identifier assigned to the application or service that you want to forward, while the IP address is the network address of the device on your local network.
You can usually find the port number and IP address in the documentation for the device or application you want to forward the port to. Alternatively, you can try searching online for the port number and IP address, or use a network scanning tool to discover the IP addresses of all the devices on your local network.
Make sure to enter the correct port number and IP address to avoid any errors or issues with your port forwarding rule. Once you have entered the information, save the settings and the new port forwarding rule should be active immediately.
Enter the IP Address of Your Server

Step 2: Access your router’s settings by typing your router’s IP address into your web browser.
Step 3: Navigate to the Port Forwarding section and locate the option to add a new port forwarding rule.
Step 4: Enter the IP address of your server in the appropriate field.
Remember to save your changes before exiting the router settings. With the correct IP address entered, your server should now be accessible from outside your network.Find Your Server’s IP Address
If you want to connect to your server from outside your network, you need to know its public IP address. To find it:
- Use a search engine: You can search for “what is my IP address” on any search engine and it will display your public IP address.
- Check your router’s settings: You can access your router’s settings and check the WAN/Internet status page to find your public IP address.
- Use a website: There are several websites that can display your public IP address, such as whatismyip.com and ipchicken.com.
It’s important to note that your public IP address may change periodically depending on your internet service provider (ISP). In some cases, you may need to use a dynamic DNS service to map your changing IP address to a domain name.
Test Your Port Forwarding Rule
After creating a port forwarding rule, it’s essential to test it to ensure it works as expected.
You can test your port forwarding rule using various tools, such as telnet, ping, or port scanners.
Use the telnet command to connect to the target server’s IP address and port number to verify the rule’s functionality.
The ping command can also be used to check if the port forwarding rule is working as expected.
Verify the Port Forwarding Rule
After creating a port forwarding rule, you’ll want to verify that it’s working correctly. To do this, you can use a port checker tool to check if the specified port is open and accessible. Simply enter the public IP address of your network and the port number you specified for the forwarding rule.
If the port checker tool reports that the port is open, then your port forwarding rule is working correctly. You can also test the rule by trying to access the forwarded service from an external network, such as by connecting to your server from a different location. If the service is accessible, then your port forwarding rule is set up correctly.
If you find that the port is not open or accessible, double-check your port forwarding settings to ensure that you’ve entered the correct information. You may also need to check your firewall settings to make sure that the traffic is allowed through. It’s also possible that your internet service provider is blocking the port, in which case you may need to contact them to request that they unblock it.
Troubleshoot Common Issues
If you are having trouble with your port forwarding rule, here are some common issues and how to troubleshoot them:
- Incorrect port number or IP address: Double-check that you have entered the correct port number and IP address for your server. A simple typo can cause the rule to fail.
- Firewall settings: Make sure that your firewall is not blocking the incoming traffic on the port you are trying to forward. You may need to create an exception in your firewall settings to allow the traffic.
- Router firmware: Outdated router firmware can cause issues with port forwarding. Check your router manufacturer’s website for firmware updates and install any available updates.
- Multiple devices using the same port: If multiple devices on your network are using the same port, this can cause conflicts and prevent the rule from working. Try using a different port or assigning unique ports to each device.
If you have checked these common issues and are still experiencing problems, you may need to consult your router’s user manual or contact your internet service provider for further assistance.
