 By default, the unipi-lte Linux service provides automatic handling with the default network gateway according to the WAN availability on both main and backup network interfaces. The main network adapter is usually wired ethernet (eth0) while the backup is realized by the LTE modem. In the Linux routing table, the default GW routes for both of these interfaces should be always present. When a "swap" of these interfaces is necessary, the unipi-lte daemon automatically increases/decreases their metrics. By default, the unipi-lte Linux service provides automatic handling with the default network gateway according to the WAN availability on both main and backup network interfaces.

-Therefore, it is necessary to continually keep the metrics as positive non-zero values. This is ensured by a DHCP client when DHCP is active on the main network interface, but **it must be assured manually if static IP is configured on the main interface** (as static routes have zero metrics as default). As an example, you can put a constant to the interface’s configuration file at ///etw/network/interfaces.d//.+Therefore, it is necessary to continually keep the metrics as positive non-zero values.
