T-Mobile Home Internet Review
I have been using T-Mobile Home Internet for a couple of months now. I recently upgraded to the 5G Gateway, which has made my WiFi much better Vs. the LTE Gateway which sucked and had a lot of restri...
Unfortunately, it goes deeper than just allowing you to set forwarding rules in the router... be that manually or via UPnP.
Unsolicited inbound traffic is not properly passing through the forward facing layer. It is a problem inherent to the 464XLAT approach they implememted to support dual IPv4 and IPv6 addressing.
Until they switch to a better method of managing IPv4 traffic through their IPv6 only network, there will be issues.
I have found a solution with one VPN provider, but the extra features to make it work would cost an extra $16/month--and that is at their best annual subscription rates (one year of static IP plus 2 years of VPN) Windscribe is the only one that I have been able to confirm they have a strategy to do specifically what is needed to truly get around this mess.
One of the core issues is bound to the fact that the public IP you wind up with is not actually JUST your IP--it can still be shared with others using the same service. So basically, you need to be securing that public IP for your use in order to forward ports properly. This is what ramps up the cost at Windscribe.
Many offer P2P support through the paid side of their VPN services, but it only works partially... basically where you can use stateful inspection and such. It gets around issues with BitTorrent and such... but does not necessarily work for unsolicited inbound connections, which can break some P2P communication with games--especially if that game is running on a console.
The TLDR: until TMO restructures their core network topology for the service to more properly support dual-stack IPv4/v6, problems will persist regardless of what is going on with their modems.
