Home Internet Port Forwarding working in 2021?

I see a couple threads talking about port forwarding not working and I still can’t seem to get mine working.  Is anyone having any success with new hardware or contacting support?

I just got the LTE wifi gateway yesterday and do not see anyway to even setup port forwarding. I called support yesterday, was on hold for several hours, the "tech" who took my call didn't seem very knowledgeable at all. So, nothing was resolved. 


I called again today, a message stated it would be approximately 2 hours and would I like a call back, so I said yes to set that up. 6 hours later, they call, and I am put on hold for 40 minutes, then the phone went quiet. I finally hung up. 


Looking through the available settings, I don't see anywhere to setup port forwarding. There are very little options. It's as if it is setup for the most basic non-technical user, who they don't want touching anything. It's disappointing. 

I'm guessing that we may need to get another router and connect the T-Mobile router to the wan port? Frustrating, because before signing up, I made my requirements clear and they assured me their service would allow them. 

I have been using t-mobile hotspot and other carriers for years and have also had issues with the port forwarding. The issue is that t-mobile and others use a carrier grade NAT which will never assign you a public IP when connecting to the internet. You will be assigned a shared IP to WAN which means there is no way to direct any particular port to your device directly. Unless t-mobile offers a service to allow a public or dedicated IP this probably will never be supported, even if the router they provide has it available in their settings. 

However, I have found a decent work around that has worked well for me, though I am still waiting for my device to come in for me to try on the t-mobile home internet. It works well with my phone tethering and hotspot though so I assume it will work the same. PureVPN has a service with their VPN that assigns your connection with a dedicated IP address and port forwarding. It works with PPTP and L2TP / ipsec only but this makes it very easy to set up. PPTP is hardly encrypted and is not standard to use for many VPNs, but it is very very fast and is minimal on latency / bandwidth compromises. 

I use a second router with dd-wrt firmare and use PPTP to connect straight through its WAN connection settings. Super easy to setup, and the dedicated IP you assigned becomes the WAN IP of the second router which means port forwarding is used directly. No need to open any ports or DMZ with the t-mobile router at all. Routers will vary with PPTP WAN support, but this should be a pretty common protocol so others might work the same. 

This is actually easier than it might seem, and it works better than you might expect. The benefit is that you will also have a dedicated IP which is super handy to have. The downside is that there is a cost to these services, but PureVPN also supports OpenVPN so you can use to connect other devices as a standard VPN. Its a work around, but so far its the only way I have found to poke holes through that wall. 


Ok found this it may help some ppl. 

Fix Double NAT on an Xbox, router, and PC




THIS IS A MAJOR PAIN IN THE … i switched over to tmobile wifi, and it killed my xbox games on my pc.

so…. i have been trying everything i can to resolve it.  now will try the ethernet cable.  if that does not work i will have to say goodbye to TMOBILE

and the thing is, THEY KNOW this issue exists.  the engineers knew it when they rushed it to market.  and the rep’s you sit on the phone w// for hours are clueless to resolve it.    and when the rep says they will follow up …. don’t hold your breath

   thanks Tmobile!   your the best at killing my gaming
