Can't get port forwarding to work no matter what.

Hello, for the past week I have tried just about everything out there to get port forwarding working. So far, I've tried:

-Setting the port forward (obviously)

-Following the guide on the Xfinity page

-Scouring the internet for answers 

-Resetting the router

-Factory resetting the router

-Ensuring there is no static IP

-Re-installing windows on my device 

-Releasing the Ip on my device and renewing it

-Setting ipv4 as priority on my desktop

and more

There has not been a single hint of port forwarding actually working and the current side-issue is now that I've released the IP again, the XFi webpage shows the wrong IP (10.0.0.57) instead of (10.0.0.108).

What am I missing? All I haven't done so far is replace the router itself.

@User_349284  Thank you for bringing this to our attention. We would love to be able to figure out this port forwarding for you. Are you using an Xfinity rented modem or your own?

@XfinityTimothyA​ Thank you for your response.

I was using the Xfinity rented XB7 modem. Since creating the post, I actually did end up swapping out the modem and calling support to have them diagnose the issue but the issue persists. They even said that to multiple people on their end the port forward was 'grayed out'. I was escalated to the next level, we ended up putting the XB7 into bridge mode and using my Eero router that I have hooked up to it, however, the port forwarding wont work on the Eero either! I am beginning to think it's something wrong with the network in itself. 

If needed, I still have my old modem/router combo that if worst comes to worst we can try that.

@User_349284 Thank you for letting us know. When you spoke to our Advanced Repair Team, did they set up a ticket for you? 

I no longer work for Comcast.

Hi, No the advanced repair team did not set up a ticket of any sort. 

Afterwards, I did some more troubleshooting on my own - I got bridge mode to function properly with the Eero, set up the port again with the Eero after ensuring my Eero had the right device selected, and then tried again. 

This time, with the server I was trying to access turned ON. 

It worked - I felt like I giant idiot after two weeks - and the problem has been solved. I figured it would register a port as functional regardless of if the program was launched but I suppose that is not the case.

I still don't think I can edit my port forwards still if I were to switch back to my xFi gateway but it doesn't matter at this point. Anyway, hopefully this can assist other people who may be searching for a solution the same dumb mistake I made.

It's great you were able to get things working on your end, though I apologize we weren't able to get the XB7 port forwarding working for you. It's also great that you shared your solution as well, so others can see how you got things completed.

 

Since things are how you need them now, would you be willing to mark this post as resolved with an accepted solution?

 

If there's anything we can do for you in the future, we're always here for you 24/7.

I no longer work for Comcast.

@User_349284​ It's not just you having this issue. It's seems everyone that needs to port forward can't right now because port forwarding is broken. First it was not being able to add them, now it just shows the wrong IP address and doesn't forward the ports even if it is the right IP.

 Port forwarding not working (existing since 1 year ago) and not being able to create/delete any. Tried reseting modem/switch/router and even set modem back to defaults. I created them before so i know how to do it and it fails now.  Whenever I contact Xfinity all i get is the "article you have requested email" which is a link to "how to create port forwards" which is not my issue. We know how to create/delete them but cannot anymore.

Specs:

modem:XB7 model:CGM4331COM Hardware 2.0

I noticed this problem in March and was sent this modem in Dec 2021 to replace my working XB6 which (again) had port forwarding working with no issues. I have emailed xfinity support and direct message as I saw in these forums to do.  I saw this in another post and I confirmed with packet capture on my router.  PLease have DEVS fix this asap or atleast give us an option to do it manully.  Send this to devs and it should help them see the issue faster.  You cannot add/delete/change port forwards from the app or webpage (myxfinity)  app version:4.6.0.20220420174048 (whish i had an older version app which worked)

The request to set port forwarding rules seems to be missing authentication credentials.  The network request returns a 400 with the following payload:

{ "code": "033", "title": "Invalid Request For Create Port Forwarding Rule", "status": 400, "detail": "401 Unauthorized: [missing authentication credentials\n]", "source": "xficov_config_sets", "type": "https://github.comcast.com/xfi-coverage-platform/api-spec/blob/develop/error-code.md#400-033" }

Had this problem for weeks. I have a ticket in but have not heard of any resolution. I decided to buy an Arris T25 router and TPLink router. I will set up next week.
