T-Mobile Home Internet - Setup Fixed IP
How can I set FIXED IP's? I need fixed IP for my printer and cloud device, because with DHCP, every time I restart devices, with random IP, I lose mappings and have to refresh settings all the time.
You can get a an additional cost fixed external IP address with a T-Mobile Business Internet plan, and some users have gotten fixed IP addresses by using various VPN services.
Don't blame the router for this (although there IS a lot to complain about in the way they've locked down the routers in firmware).It's not the router, it's the service outside your house, after it leaves your router, that causes the inability to get a fixed IP address via router settings. It has to do with T-Mobile's infrastructure, using 464XLAT and CGNAT to translate IPv4 addresses into IPv6 addresses to move data over their network and then translate it back to IPv4 addresses at the other end (and again on the return trip).
Getting a fixed IP address is going to cost extra, whether you use a T-Mobile Business Internet account with fixed IP address or a third-party VPN service with fixed IP address capability.
