when usb modem gets connected system, changed lan metric 4237. , usb modem gets metric lower value between 4-10.

lan ip : 10.12.1.13 4237 (metric) usb modem ip: 101.63.220.237 6 (metric)
now default network interface usb modem because has lowest value of metric.
problem: local application able connect default network interface (metric-6) cant connect lan network interface access internet (metric-4237).
scenario 2: changed metric of lan 4237 12 (or value lower value or near value default network interface), local application able connect lan well.

persistent routes:
queries:
what metric range (min-max)?
why application not able connect lan when metric value 4237?
please suggest correct way use metric?
