Static routing is used to add a routing table entry (BMR200 Industrial 4G Cellular Router as a sample).
Interface: to choose which interface you want to add routing
Target: can be a host IP, or subnet
IPv4 Netmask: the netmask of subnet, if the target is host, the netmask shall be 255.255.255.255
IPv4 Gateway: the address of next-hop gateway address. Note: this address shall be achievable, or you’ll fail to add static routing.
