port forwarding not working.

I followed the instructions here:

https://www.xfinity.com/support/articles/xfi-port-forwarding

It appeared to work yesterday, but since then, it has stopped working. I turned on the advanced security and got a bunch of security events. I wonder if that caused it to stop working. Not sure.

Since then, I've factory reset the xFi gateway and it still doesn't seem to work though. From inside the network, I can reach the non-privileged ports connecting to the WAN IP, but from outside, no ports.

Is there a way to re-enable the port forwarding on the xfi gateway itself? It appears that it can be configured only in the App. I've configured it in the app and even tried enabling DMZ. Doesn't matter. Just doesn't work.

Appreciate any help. Oh, and I've tried tech support. I've asked to escalate also. I still get people that don't even know what port forwarding is.

I figured it out. It was DHCP. the node needs to take a DHCP whenever the lease expires (mine was 1 hour even though the UI shows 2 days.) I ended up getting another gateway and setting the xfi into bridge mode. Sad that it has to be this way. The xfi gateway has very good hardware.

I had the same problem and purchased my own (approved) Motorola gateway. Even with this new gateway, port forwarding DOES NOT WORK. It has to be something being blocked above the local gateway by Xfinity.

@richardberthao​ Any progress on a fix for you?

I bought a Motorola MB8611 from Amazon and I'm unable to activate port forwarding. I bought the Motorola because Comcast told me I had to replace my modem. This Motorola MB8611 was on their list and available quickly from Amazon. Port forwarding had become intermittent and unreliable on the old modem when I get the email early this week that Comcast wanted me to replace the modem, so I did that. Now port forwarding doesn't work at all. 

All the documentation I can find on port forwarding seemingly only addresses the use of the Comcast owned (and rented to a customer) modem which I will not do.

Are you sure that you can't get the port to forward if you just reset the networking on the device? That's what I did - just set IP reservation on the xfi and then reset the networking on the host and it would pick up the same IP from the xfi again and port forwarding would work again. I chatted with another person that said they did everything and couldn't even see the device to forward to. I kept the Xfi as my modem because I need the unlimited data. The Xfi is a decent piece of hardware. Just bad software.

Port Forwarding not working

I have tried for weeks to get Port Forwarding to work. I spoke with 2 Support reps that got frustrated and cut me off. One said google it the other just hung up.

spent money on software hoping to fix the problem, but nope. The devices needed are not showing in the list tho running on the Network.

This has been an ongoing issue for years now. I personally have been having this issue for almost a year. Had the gateway replaced for that reason. Started to work and now 5 months later doesn't again. Get rid of the ridiculous app and put the control back in the gateway like it should be.

@user_cb92fd Are you attempting to set that up on an Xfinity modem or your own modem?
