With each passing day, the number of internet technologies is increasing because internet consumption is expanding considerably. One such internet technology is port forwarding, which has been designed to be a simple process. However, the process has been made difficult because people have been dealing with downfalls on the Xfinity internet.

A small problem is port forwarding can lead to huge issues, and we have outlined all possible troubleshooting tips in this article. But before that, let’s strengthen the concept of port forwarding. So, port forwarding is the process in which data is interpreted by the computer network and directed to the desired IP address or a port,

The direction process is optimized through the router or a host because different setups have different prerequisites. It is advised to use the tester programs for solving the port forwarding issues. In addition, the tester programs are responsible for showing the active IP of the computer system, which is essential for fixing the issue. So, have a look at the troubleshooting tips!

Xfinity Port Forwarding Not Working

1) Firewalls

You might not be aware of this, but the majority of operating systems already have operating systems installed into the system. This means that firewalls are always running in the background even if you aren’t aware of it. In addition, the anti-virus programs are integrated with the firewall feature that tends to outshine the internet connection, and the pop-ups are automatically blocked.

Similarly, the router will be integrated with the firewall as well to ensure your device is safe from unsafe internet connections. It is advised to uninstall the firewall. In addition, make sure the drivers of firewalls are uninstalled as well because they need manual and separate uninstalling.

2) Broken Windows Firewall

The presence of a firewall might be the issue, but the disabled or broken firewall will lead to higher issues. For instance, the firewall might not be updated or properly installed. So, make sure you have a single and properly installed firewall.

3) Multiple Routers

When you are working on port forwarding, and more than one router is connected to the device, the functionality will be adversely impacted. So, you need to log in to the router and write down the available IP addresses. After that, enter the IP address int eh DMZ page and apply the settings. These settings will optimize and direct the connections on the correct side (read router). This way, you will know that all configurations are coming through one router.

4) Same Port But Different Routes

If your router is busy in ruling the port forwarding in one place or another, the router checks will be skipped. This is because if two port forwarding options are working at the same port, the outcome will be zero. In this case, you can remove one of the two-port forwardings to ensure one port has one connection.

5) Interrupted DMZ

If the port forwarding rule isn’t getting implemented or the rule isn’t ready, there are chances that the DMZ page isn’t working as it’s supposed to. This is because DMZ pages open the port rules but cannot work with the rule. In this case, you need to ensure that DMZ page settings are properly configured. For instance, if you need to make the port forwarding rule work, make sure the DMZ is disabled.

6) Wrong Computer Name

The routers tend to work by listing down the computer name rather than the IP addresses. This means that it can come up with different computer names with different IP addresses. In this case, you will need to reboot the router and make sure all the extra listings have been removed. Also, you can manually check the connections that you are working for you and delete the other ones!

7) Virus

For everyone out there, the virus can be the prime culprit of tarnishing the port forwarding. These viruses negatively impact the device’s performance. This ineffective performance can be seen in the connections as well. So, run regular virus scans to ensure your network is working optimally, and the port forwarding will work with zero downfalls.

The bottom line is that port forwarding issues are usually caused by routers and devices. So, you can also start with restarting the devices. Also, if you download and install some updates, always restart the PC before using them!

  1. Look I’m going to assume anyone who is looking into “Port Forwarding” on an Xfinity Modem/Router Is a person who already knows a thing or two about port forwarding…

    Like me, you are probably a person who let a Comcast associate talk you into getting a brand new fancy-looking modem with illusions of blisteringly faster speed than previously. anticipated…

    So now here you are fighting with trying to get your Minecraft Server hidden in your closet or any other internet of things you had running behind your Linksys router that you updated to DD-WRT…

    I fought for hours trying to get this to work… The firewall feature is disabled, log into the fancy, what looks like it should be a powerful interface directly on the Modem forces you to use a crippled web app to no avail…

    SO – if you still have your DD-WRT Appliance and you don’t care about using the onboard radios that don’t reach as far anyway and force you to use crippling security that doesn’t work well anyway, Waste no more time and look no further than here:

    Put the Modem into Bridged Mode, put your DD-WRT WAN interface back on DHCP, Update your Dynamic DNS of Choice, and Marvel as all the “Internet of Things” hiding in your Closet work Again…

    You’re Welcome…
