Hello,

I'm using a Teltonika RUTX12 Dual 4G Router

I want to configure it according my needs but i't difficult as I'm not a network expert

The configuration that I need is:

SIM CARD 1 Internet --> Wired (LAN) Devices

SIM CARD 2 Internet --> Wireless (WiFi) Devices

WAN Internet --> Set as failover for both Sim cards

SIM CARD 1 has Public IP (NO NAT)  because I need to access 1 or 2 devices that are LAN connected.

Devices that I need to access from outside have internal IP 192.168.1.55/56

It is important that those devices can be reachable on SIM 1 IP

Also need to configure DDNS for reaching SIM1 Devices even if public IP changes

Can I do all these things with my RUTX Router ?

Thanks to all in advance!

Hello,

This article provides a guide on how to separate mobile data traffic by using first SIM card for LAN traffic and second SIM card for WLAN traffic. These configurations are specifically made for RUTX12:

Thank you! 

I followed this guide: https://wiki.teltonika-networks.com/view/Splitting_Network_Traffic_Via_Multiple_Interfaces but I have encountered a problem: 

PRIMARY MODEM: Connected

SECONDARY MODEM: Disconnected 

Secondary modem is always disconnected even changing SIM cards 

I need to have both modems active

As one is for wireless devices and the second is for Ethernet devices.
