Port Forwarding issue

I've had the same issue since "upgrading" to the new router. Several attempts to work with support have also ended in dead-ends. I'm beyond frustrated with this issue and find it hard to believe that an ISP does not have at least one person on staff that knows how to deal with this issue. Trying to work through the support channels is extremely tiresome.

An issue that (after much research) was fixed in two minutes on my old router is impossible to address with this new one. Advanced security is not the issue. I was able to turn that off a while ago as that is step #1 in getting my PLEX server to work. I ended up having to go the long way around to find the right menu to disable Advanced Security, only stumbling on it while poking around the site in the troubleshooting section.

I'm about ready to kick Comcast out since no one seems to be able to address this issue.

Hi, @netz and @bmcmahon5807! Thanks for reaching out for help with the port forwarding concerns. This is definitely not the experience that we want our XFINITY family members to have. I apologize for the inconvenience that this has caused. We truly value your business and will do all that we can to provide solutions as quickly as possible. With the improvements we've made in security through xFi, we're limited on what we can do manually and with troubleshooting issues such as this. That said, I was able to find some information that may prove useful! Just so you are aware, xFi only supports port forwards to be set up for devices with an IPv4 address. If you're continuously getting an error message, this could be a cause if your device has an IPv6 address. You can find more great information, including how to set port forwarding through the Xfinity App, at https://comca.st/2PclYDF. Can you take a look at this info and see if this helps, and let me know if you still need additional assistance from there?

Thanks for taking the time out to respond, both. 

There are no troubleshooting options through comcast because the device is a wired device. It seems any troubleshooting options are only available for wireless devices. 

@comcastgabe, I went through the app and followed the steps in your link prior to reaching to out to comcast. I gave comcast the benefit of the doubt and waited a few days and tried again before reaching out, thinking it just might be glitch. I also don't appear to have any advanced security options available to me any longer, it appears to be a premium feature now?

The device in question is also currently assigned an IPv4 address using the reserved pool in the connected devices section my router admin panel. I do however, see an IPv6 address and local link IPv6 address assigned as well. I am not sure what else I can do about this because the reserved IP address is an IPv4 address. Do you have any suggestions?

Who do I send the message to? I can't seem to pull you up when I enter your name in the recipients box.

Thanks
