AT&T U-verse is a popular internet and TV service provider in the US. One of the essential features of the U-verse service is the router, which allows users to connect to the internet and stream content seamlessly. However, sometimes you may encounter issues when connecting to certain websites or applications. This is where port forwarding comes in handy. Here is a complete guide on AT&T Uverse router port forwarding.

This guide will explore the basics of AT&T U-verse router port forwarding, including what you’ll need, how to set it up, and which ports you may forward. Whether you’re a beginner or an advanced user, this guide will help you navigate the process easily – especially if you try PureVPN’s port forwarding add-on.

Things to collect beforehand

  • A computer or mobile device connected to your U-verse network
  • The IP address of the device to which you want to forward ports
  • The IP address of your router
  • The login credentials for your router’s web interface
  • The port numbers and protocol [TCP or UDP] that you want to forward

The step-by-step process to set up port forwarding for AT&T U-verse router

Here are the general steps you’ll need to follow to configure port forwarding on your AT&T U-verse router:

  1. Determine the IP address of your computer, gaming console, or any other device to which you want to forward the ports.
  2. Enter your router’s IP address [typically]into a web browser on any device connected to your network.
  3. Enter the login credentials for the router. [The default username is typically “admin,” and you can find the default password on the bottom of the router or in your router’s manual.]
  4. Find the “Firewall” or “NAT/Gaming” section on your router’s web interface.
  5. Navigate to the port forwarding settings.
  6. Add a new port forwarding rule by entering the IP address of the device to which you want to forward ports, the port numbers and protocol [TCP or UDP], and a name for the rule.
  7. Save the new port forwarding rule, and repeat the process for any additional ports or devices you want to forward.
  8. Test the port forwarding by connecting to the forwarded port from a device outside your network. If the connection succeeds, the port forwarding has been configured correctly.

It’s important to note that the specific steps for configuring port forwarding on an AT&T U-verse router may vary depending on the model and firmware version of the router. You must refer to the router’s manual or documentation for specific instructions.

Some common ports to know

Here are some common UDP and TCP ports used by AT&T U-verse routers to provide network services:

  • TCP port 80: HTTP web traffic.
  • TCP port 443: HTTPS secure web traffic.
  • UDP/TCP port 53: DNS resolution.
  • TCP port 25: email transmission via Simple Mail Transfer Protocol (SMTP).
  • TCP port 110: email retrieval via Post Office Protocol (POP3).
  • TCP port 143: email retrieval via Internet Message Access Protocol (IMAP).
  • UDP/TCP port 1194: Virtual Private Network (VPN) traffic.
  • UDP port 1701: L2TP VPN traffic.
  • TCP port 1723: PPTP VPN traffic.
  • UDP/TCP port 5060: Session Initiation Protocol (SIP) traffic for VoIP services.

Please note that these ports may be used for other services or applications depending on the specific configuration of your AT&T U-verse network. Additionally, some of these ports may be blocked or restricted by the network administrator or ISP, so always refer to the router’s documentation or contact support for specific information.

Your solution to bypassing the CGNAT gateway

Port forwarding with CGNAT [Carrier-grade Network Address Translation] is tricky because it involves sharing a single public IP address among multiple users, which can cause conflicts when trying to forward ports to a specific device. 

Like many other ISPs, AT&T U-verse uses CGNAT to conserve public IP addresses, making forwarding ports on the U-verse router challenging. With CGNAT, the public IP address assigned to your U-verse router is not unique to your device, making it difficult for incoming traffic to reach the specific device to which you want to forward ports. 

This can cause connectivity issues and requires more advanced techniques like port triggering or VPNs to work around the CGNAT restrictions.
