Story time: It depends on the hardware at your disposal. I'm now on the new T-Mobile Home Internet service, the router+wifi device supplied (a Nokia 5G LTE based unit with a SIM on one side) firmware has basically no configuration - you cannot assign static DHCP, no bridge mode, no port forwarding - it has UPNP on or off, that's it. A truly sparse webUI, frustrating no-config device at 1.0 firmware level that doesn't even show you what the DHCP ranges in use are. My G-Shock watch has more configuration options than this thing does. :-/
