Can't Port Forward

@XfinityPeterH​ Great! So, again, I have gone through every single step listed above. At this point, the Admin Tool port forward page shows this:

And the app shows this:

@THex, We would be happy to assist you with the callback and troubleshooting with the app. If you would like our assistance, please send us a DM with your name and full address by doing the following: Ensure you are first signed in, then you will see an icon at the top right of your page.
From there, click the 'New Message' icon. In the 'To' field, type 'Xfinity Support'.
Type your message in the text area that appears at the bottom of the window and hit enter to send. An official employee, such as myself or whoever is first available, will respond.

@XfinityPeterH​ I really dislike your generic response. [Edited: "Inflammatory"] Your somehow not responsible and you've painted the path so clearly for us lol. Do you not know or notice or care that everyone's complaint is that? And by the way this is for like 3 years now. I've backtracked it and walked, you people say that you provide the opportunity in the software for port forwarding, but it's broken and I'm supposed to find that to be an accident and not intentional. Which by the way it is absolutely intentional. Suddenly Xfinity employees don't know anything about the internet and they're only job is to provide you with internet speeds. Fine let's say I'm willing to accept. All you need to do is give me internet speeds and the rest is up to me. You can't put out fake software that leads people places that doesn't work. And additionally, but this is the most important part. If internet speed is all you care about, you still are absolutely responsible for the quality of that speed which implies and infers [Edited: "Language"] a lot more than me hitting the mark of what I pay for. Again, hitting the speed mark is only ever proven programs paid for and made for Xfinity internet speed testing. Any other apps I use not made by xfinity always show that my speed is not what I pay for to which the response is constantly, well we provide "up to" insert what you're supposed to get here. Great, how about from now on my end of the bill says I provide up to the amount we agreed on and then I just pay what I feel like you know like you do. Additionally, if you provide up to the speeds I pay for that would imply in fact be a guarantee that at some point, even if only for a moment it hits those speeds... Yeah take a wild guess what I never does. [Edited: "Inflammatory"/"Threats"]

I completely understand the frustrations, @THex! It certainly is not what we want or intend. We can certainly dig into further troubleshooting with the Xfinity App, and the features available to you. I know you mentioned you have reached out on numerous accounts regarding the error that you receive, and I would like to further dig into it on our end. Can you please DM us? 

Will you please send our team a direct message with your full name and full address?

Been having the same issue here. It seems to have started happening with the last update to the Xfinity application on April 26th.

@jesserbyars​ Thanks for the tip, much appreciated. You got me thinking that the Xfinity app for iOS might work better, so I'll be installing that on my wife's phone a little later and trying that out first. I use a largely de-googled Android variant and am trying to keep it that way, but if the iOS app suffers from the same issue I'll have to bite the bullet, install vanilla Chrome, and use your method on my Android device.

@jesserbyars​ YOU ARE MY HERO!  This worked!  So the app's UI is just broken, and has been for a while.... but you can use the links from the chatbot to navigate to the screen to set up port forwards.  It's simply amazing that Comcast/Xfinity hasn't fixed this yet, since it's a simple navigation issue within the app's UI!

@rf2906​ Happy to have helped! I went to Xfinity chat to talk to an internet agent to tell them I had found a solution. They did not seem to understand what I was saying, and immediately sent a refresh signal to my router for absolutely no reason. This caused my router to fail to reconnect in some way and I was stuck troubleshooting with a supervisor for 90 minutes before I was back online. I knew they had often done this (sent a refresh to my router without asking) in the past when I had gone to chat for support, but this is the first time they admitted what they had done. This anecdote isn't particularly relevant here, but I just say this to illustrate that every experience with Xfinity support is utterly absurd like this in some way. They know there is an issue with port forwarding, there are many threads on the forum. It is not clear whether their failure to address it at scale is incompetence or malice.

@jesserbyars​ I too have been on the phone with support for well more than an hour.

they wont acknowledge any problem..... finally last texh i talked to told me that i shouldnt need to foward ports bor dmz z box as most people dont have the need

I have NO THAT IS VA BIG NO NO AND finally NO I need port fowarding !!  the swervice is worthless without it

IF it cant be fixed you have lost another customer

THANK YOU for Nothing

Hey there @

Thank you for taking the time to express your concerns over your port forwarding issues. Were you able to connect with our support team? 

@Blackwhisp63​ Please try my solution earlier in the thread if you haven't already. You may need to change the default web browser on your phone to Chrome temporarily to make the app stop displaying blank pages. Also, try typing "Port Forward" to the xfinity assistant in the chat section of the app. See my post for more details.

@user_4aee5e​ I just tried it to check and I can confirm that it does still work, at least on an Android phone, with Chrome set to the default browser, and using the "Xfinity" app. Please double-check the instructions earlier in the thread and try it again. And yes, [Edited: "Inflammatory"]. Good luck.

@user_4aee5e​ what port is your work expecting to be open? please hopefully it is not 3389 *edit add* and are you using a company vpn using wireshark etc?

@user_4aee5e​   make sure you type port forward. Not Port forwarding!   I just did it and it worked perfectly.  

Conformed workaround doesn't work current. The wait list is way too long for me to sit there and ask the same questions their heavy bad English representatives because that's all they can get to work our tech nowadays. I got Xfinity for myself so I can adjust this specific settings for gaming and school and now I've been screwed for a few months now because they think there's nothing wrong with their custom set of ports for the public

Hello, @Tangz! We are happy to help with the port forward! Are you seeing an error that shows "something unexpected has happened" or something different?

@user_ca0dc3​ FYI, I finally gave up on the app, as I was also having continual dropouts using the XB8 and gigabit speed. I downgraded to 400 mpbs and bought my own Motorola MT7711, and the service has been stable. So now I can control my port forwarding directly in my own router as well!

Get rid of the Xfinity Gateway, downgrade to 400 Mbps, and get a Motorola MT7711.
You'll control your own router!

@user_rtqmbm​ I haven't tried doing this at all, so I'm not certain that this is your problem, but I suspect that it is the Advanced Security setting that is blocking you. Take a look at this page, about halfway down, under "Tips To Access a Blocked Device", and if that doesn't help, try a little further down the same page, under "Disable Advanced Security": https://www.xfinity.com/support/articles/using-xfinity-xfi-advanced-security

I don't know exactly what the Advanced Security setting does, but I can tell you that I have always left it disabled and haven't personally had any issues. Hope this points you in the right direction.
