@XfinityRoberto​ I have gone this route and been asked if the Port Forwarding through the App works three times. Is there a single person that can look into this?

@user_cb9b8d I would like to gather more information about the steps you have taken.

Thanks so much for taking the time to reach out to us regarding our port forwarding options. Is this the only feature that you are running into this error through the app? Are you having this issue when attempting to access the app through all devices? 

@user_f83de8​ I always used my own routers and modems until very recently. Xfinity dropped support for some lower DOCSIS versions a few months back, and I idiotically opted for what I thought would be convenience. Never again. The hassle from using these rented devices is not worth the $15-20 of savings a month. Unexpected breakages every few weeks, locked down settings, and the Xfinity application is useless shovelware for anyone who knows the slightest thing about network administration.

Well, the "new" router seems to be working well with the Xfinity gateway set to bridge mode. Sure is nice having local control of my forwards and other settings again.

FYI the router is a Belkin F951009. Both wired and wireless speeds are normal through it. And it's a cute little thing, too.

@jesserb​ That worked, thank you. I'm a new xfinity customer and already experience a lot of frustration. It's like 1990s all over again, when setting up any new device took hours of trial and error.  Comcast is stuck in 20th century.

@jesserb​ This worked. Thank you. Put this issue out over the phone, they stated they forwarded the issue to the IT department (Aren't they all IT department?). This was many weeks ago (5+), wasn't fixed. Updated the app, wasn't fixed. This solution works. Period. Note: You need to literally type "port forward". "port forwarding" apparently is not a valid term (When it's 1 and the same).

Keywords for those googling this in hopes they stumble onto this SOLUTION ABOVE: something unexpected happened , comcast port forwarding / forward not working , can't port forward 2023 comcast , cannot use app to port forward , android xfinity app port forward broken / unresponsive

To whoever scrolled down this far - the solution is above, what "jesserbyars" stated! This works like a charm!

@jesserb​ thank you mister, for me it open the option to configure the port forward, a cup of coffee to you.

@jesserb​ This no longer works

@jesserb​ This worked, thanks!
