Good morning! Thank you for reaching out to let us know this is still occurring for you and that you have been having trouble with your port forward. Have you attempted to delete this and add the port again?

I no longer work for Comcast.

@XfinityDevinC​ Yes, at least 15 times I tried, including modem and gateway resets. There is clearly a logic error on your backend. If this is not addressed soon, I will be forced to either at minimum replace the modem routing (bridge) or worst case purchase a new modem (and router) at which point I will send the invoice to Comcast  ;-)

I started having this problem on Thursday, April 7.  Before that, I was not having any issues with port forwarding.  I already tried factory resetting my gateway, but I'm still getting the error.  

I'm unable to set up port forwarding for my Desktop computer, which is connected via Ethernet.  However, I was able to set up port forwarding for a different device (Nintendo Switch) without any issue.

Hello @user_f3d2cc Is this issue still present on your Ethernet connected desktop? Has the port forward to the Switch remained active and strong? When attempting to set up the port forward, are you using the XFi App or going through the Admin tool?

Same, it also deleted what I had setup when it did work. Paying over 200 a month for everything we have here and cannot even use it.

@XfinityAlfonso​ When attempting to set up port forwards, I have been using the XFi App.  I am unable to set up port forwarding using the Admin tool, since the port fowarding section just has a link saying "Managing your home network settings is now easier than ever. Visit xfinity.com/myxfi to set up port forwards, among many other features and settings."

However, I did have a workaround for this problem; when I disconnect my desktop from Ethernet (and have it use Wi-Fi instead), I am able to open the port without an error.  My desktop has a different internal IP when connected via Ethernet (10.0.0.144) compared to connected via Wi-Fi (10.0.0.18).

As for my Nintendo Switch, I didn't actually try to use its port forward for anything.  Opening up the Switch's port was just a test to see if the system would give the same error for a different device.

I'm having the same issue. Why we can't set this up in the GUI interface of the router is beyond me. I have three ports I need forwarded and at this point will have to use dmz instead until this is fixed. I have been in IT for 25 years, I can program my own router without the need to use an app or a website, just let us assign theses settings locally.

Months later, this is literally STILL not fixed. To make matters worse, it has deleted the port forwards I had setup in the past when it did work! This is absurd that months later it is still going on.

We have spent 48 hours on and off the phone with xfinity and there is not someone there that seems to have the ability to get into the port forwarding function of my modem.   Anyone have a number to call to someone who has access.   This is rediculous.

Please put in a ticket!  The issue needs to be resolved.  The message I keep getting when I select Port forwarding is:

If the problem persists, check back later.

Anyone ever get anywhere when you DM support and take it off line? From the comments clearly the phone call doesn't work... 

Now I have this problem. And I was also struggling with this one

I was online with DM support for many hours today and they were not able to resolve my error when trying to reach the port forwarding functionality.  One solution they suggested was to factory reset my xfinity modem/router - to which I said no, because that would cause me to lose my existing forwards.  Another suggestion was to put the modem/router in bridge mode and use a second router........  sure, but then I would need to buy said second router......

Finally we decided that they would send me an upgraded modem/router and see if the issue persists.  I will follow up when I receive the new modem.  My expectations are low and I am already researching which secondary router to purchase.

They advised me that a ticket was created and sent to the 'Backend Team', so maybe (but I doubt it) someone will look into the issue.

@user_5aa3c9​ Bridge mode does not work on mine either. Once in bridge mode, I get no internet connection to either port on the xfinity modem so there goes that idea. I have the newest modem / router with home security so I do not think I can upgrade anymore. They have simply messed something up.

I tried the direct-messaging and this was the answer "Residential accounts can not have static IP. This is why it is not working." Say What??? It has been working for over 5 years, why is it not working? They will not answer that.

@user_832d5d​ LOL, same for I've been with them for 10+ plus years now. Never heard of that, getting random answers from support staffs... Currently no one have real answer or fix for it. Sounds like firmware updates and API issue. Crazy!!!

So, the official answer from Direct-Messaging is that Port Forwarding does not work on residential accounts. You have to have a business account now. I asked to see this in writing, but they could not provide anything in writing. I asked why this has changed and they just tell me to purchase a business account.

@user_832d5d​ Is it possible that the tech was incorrectly assuming that a static external IP is required for port forwarding of local IP's (which would be static) and then used his 'knowledge' that only business accounts can have static external IP's and stated that port forwards are only available on business accounts?  

I find it absolutely absurd that: 1. If true, they would impose a port forward limitation based on account type, or 2. if not true, this is the type of support we get.

I was able to add a port forward on my laptop's ethernet connection, but not the new mini-computer with ethernet I'm setting up.  It's not a business/residential issue.  But after 4 days of trying, all of my network settings are identical between computers and the mini will still not port forward.

@user_99661f Are you using a Xfinity provided modem or your own equipment? If you are using a Xfinity provided modem I would recommend checking out Set Up Port Forwarding on Your Xfinity Gateway

Something that worked for me.  

I know every setup is different, but here is how I got around the use of port forwarding on my xfinity modem.  In short, I used the UPnP functionality. 

 

I was able to get 2 different methods working:

  1. Since I use BlueIris to monitor my cameras I was able to use its Webserver functionality – “Use UPnP to automatically add this rule” to create a single open port to BlueIris. In this way I could just assign all my cameras to BlueIris and not need individual port forwards.

Xfinity router initially would not accept the rule so I went into the modem Admin page and ran a reset on the Wi-fi router (Troubleshooting ->Reset/Restore ->Reset Wifi router).  I don’t know why it worked because the pc running BlueIris is connected via Ethernet, but it did.  The port was opened.

 

BlueIris has a decent web UI3 that can be viewed on your phone, but for $10 you can get the BlueIris app that is much better.

  1. Another method I was able to get working was the UPnP function on the video server itself. I run 3 Geovision servers and set each to UPnP enabled.  I could see that they were sending UPnP commands using the ‘UPnP Tool’ app.  But the ports stayed closed.

I found that the Xfinity firewall was blocking the ports.  So I set the firewall to the lowest level and this opened the ports.  Then I stepped up the firewall level one option at a time until I was back to my original (medium) level and the ports have remained open.

 

I have rebooted the router and the servers and everything has remained open.

 

Maybe this will help someone.  I understand that UPnP is frowned upon, but hopefully my local security will keep the bad guys out.
