Netgear R7500 Kernel Modules for cdc_ether and rndis used by couple of 4G Modem like Hilink

As I`m LTE / 4G user I tried to compile me some more kernel modules which I needed to get my ZTE MF823 Modem connected to my Netgear R7500 Router. The Router is running at the moment the OpenWrt from myopenrouter.com but there isn't much Kernel modules and additional software implemented. Anyway those modules also should work for the official Netgear R7500 Software as they are running there also OpenWrt (old) with the same Kernel Version as the myopenrouter.com version.

For the ZTE Modem above I need some additional modules to get the Modem working with the Router. The modules itself you can find here:


ZTE MF823 4G - change IP of Modem and get Public IP forwarded to the Router...

The ZTE MF823 4G Modem is a kind of Modem which you Plug in to the Router or Computer and it should just work. Yes it does.... You Plug it in and the connection is already established.

This makes since a bit more difficulty as the Modem has its own DHCP and IP Range which it uses. The Modem has also its own Firewall which blocks all incoming traffic. As I have a public IP and use the Modem with my Router, I would like to get the WAN traffic forwarded to my Router.

I couldn't manage (yet) to get the real "Port Forwarding" working, but as after the modification I could use the DMZ where I entered the IP of my Router. So this means that all the traffic coming to the public IP will be forwarded to the Router where the Router Firewall will block stuff if needed.

For the connection to the Modem we just need to do a telnet which can be done from Windows or Putty which I prefer. The IP for the ZTE MF823 4G is standard 192.168.0.1 what I didn't change yet.


The Login and Password are the below:
Username: root
Password: zte9x15

After successfully login to the modem it should look like this:

 OpenEmbedded Linux 9615-cdp
