[SOLVED] How to access the modem (which is in bridge mode)?

Finally! :clap:

The newly created modem interface must have a random IP in the modem's subnet and not the IP of the modem itself. That was what I was doing wrong!

Thank's a lot @moeller0 !

So... to sum up:

  1. If the LEDE router is at , set the modem at a different subnet, e.g

  2. Create the modem interface in /etc/config/network

config interface 'modem'
option ifname 'eth1'
option proto 'static'
option ipaddr ''
option netmask ''

  1. Add modem at the wan zone in /etc/config/firewall

option network 'wan wan6 modem'

And you're done!

Once again thank's a lot guys!
