Hi there,
Im using banana pi r4 with quectel rm551e gl, using it for cellular and router for my home network, however my home network is so big and it gets bigger, i connected 4 other WANs connection but i feel like im getting ip conflict is there ways to avoid such problem? .... i already selected FORCE option in openwrt lan connection " force this dhcp server over anyother detected dhcp server"
Thank you 
.
Can you show /etc/config/network and ubus call system board
Doubt you will have IP conflict for a home network no matter how big network you have. The simplest /24 network have 250 addresses to give straight up.
But why do you have more than one dhcp server in the network to begin with?
Maybe you could provide more information here... it currently sounds like you're trying to bodge your way around a possible issue.
You are stating that you have multiple ways and apparently one lan??
Let's start here:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
There will be some followup questions, but this will help us understand at least what's currently setup in the config.
Hi psherman,
this all the commands output i did through ssh
root@ImmortalWrt:~# ubus call system board

First you are not using openwrt, second no signs in your config from mobile modem.
You must ask immortalwrt support xhats on github, not here.
Ah well .. you are right and im sorry abt it. at least problem solved
thank you guys
