Hello,
Recently, I purchased an LTE router from a mobile operator, but unfortunately, it doesn't have the option for LTE bridge mode. Therefore, I installed OpenWRT with the intention of turning this router into a transparent LTE modem. I managed to configure the LTE connection using the QMI interface. However, I'm not very familiar with OpenWRT software, and to be honest, it overwhelms me with its capabilities.
The problem I'm facing is that I don't know how to configure the LTE interface to transparently pass the traffic to a better Cisco router, which would serve as the main router in my setup.
I tried searching for solutions on my own, but unfortunately, I haven't found anything specific. Could you please guide me to the appropriate articles or provide instructions on what I should configure to achieve my goals?
P.S.
By the way, let me explain the situation I would like to achieve. In another location, I have internet access provided by an ISP through a copper cable. By contacting the helpline, I can switch the inferior router provided by the ISP to bridge mode and connect it to my better router, which handles all the logic. However, in the location I mentioned earlier, this option is not available, and the connection must be made using 4G.
