How to do ip passthrough in openwrt with modem interface?
Depends on the modem. But will be good to clarify what kind of modem you meant.
My device is 5G device and it has rmnet_data0 interface but we can't bridge this interface to lan directly.
I want to pass rmnet_data0 ip to single lan client
Please be more specific - what is the device and how it is connected to the router.
Device is basically a 5G Modem + Router
That doesn't really narrow it down very much. There are many 5G Modem + Router devices on the market.
It's USB-to-USB.
- Maybe bridge usb0 to an interface?
- Not sure how this is OpenWrt specific, since the OpenWrt won't be doing anything if you "passthrough"
Exactly. But we can only bridge apples with apples )
