Hi everyone.
I have an LTE modem with openwrt. Since the RAM of the device is low, I want to put this device in bridge mode and use it via another openwrt device. how can i do it? I am using the ncm protocol.
Bridge mode is not supported in OpenWrt. The closest thing is relayd pseudo-bridge, but it is not expected to save resources. See https://openwrt.org/docs/guide-user/network/wifi/relay_configuration but replace WLAN with WWAN.
