How to bind the interface to the 4G modem

[sanfweb]

I use openwrt with 2 E3372 hilink modems, I disabled DHCP in the modems and assign a static IP for connection.

one modem in subnet 192.168.10.x the other in 192.168.20.x

if I connect modems in turn, first the first 192.168.10.x and eth1 is assigned to it, then the second 192.168.20.x is assigned to eth2, everything works fine, but if I insert them at the same time, maybe 192.168.10.x is assigned eth2 and vice versa, 192.168.20.x is assigned eth1 and then openwrt cannot connect to modems, the static address settings are not suitable, the modems have been swapped.

So, for example, it happens when electricity goes out and when you turn on the modems, the wrong eth is often assigned.

Is it possible to somehow hard-link which eth each of the devices receives, for example by IMEI or serial number of the device?

Check in System->OpenMPTCProuter, "Advanced settings" tab that "Disable interfaces auto rename" is unchecked.
