i would like to setup a Teltonika device for 4G/5G network connectivity in front of out firewall.
I would like to have the firewall receiving the IP address assigned by the network provider, so the device acting as a modem.
Could all devices be configured this way or is this specific to gateways?
You’re right. Our gateways and routers can allow the device to assign its WAN IP to a LAN device. For 4G/5G specific device, you can go for TRB500 or RUTX50.
Basically, RUTX50 has more to offer than TRB500 like number of ports, Wi-Fi and GPS modules, and sim card slots. More information about its comparison HERE.
