NAT (Forwarding) in T-Mobile Gateway
I recently signed up for T-Mobile internet, and I am VERY disappointed that I could not even forward NAT traffic to my home security system. I saw that this was discussed 7 months ago in a previous...
On the waiting list ‘ere.
As far as I’m reading there’s passthrough which’ll let me reuse our existing network and maybe treat the modem as a dumb modem like we're doing to our ADSL modem. Our modem doesn't even do the job of providing DHCP; effectively as if we connected directly to our ISP's network.
Sin embargo,, from reading it sounds like T-Mobile is doing carrier level NAT for IPv4 similar to what I’ve been hearing with Starlink on their equipment; basically I could be sharing 18.0.12.3 between five other customers.
And IPv6 is not our silver bullet since it sounds like T-Mobile’s network is filtering requests before it even hits the equipment if I’m understanding what I’m reading.
IPv4 is a nice-to-have but at the same time it's deadweight going forward since IPv4 served it's purpose and is more of a nuisance. I can grab a IPv4 address---until IPv6 reigns supreme on public Wi-Fi---and set up tunneling and be happy with that so I can control my smart-home server wherever.
