Static Route (Route Mode for VGW-420FS/820FS)
Static route determines the routing rule during the handling of messages by the gateway. Most of
time, user does not need to configure static route. Only when there are multiple network segments
in the LAN network, these segments need to complete some specific applications, and static route
needs to be configured.

ARP
ARP or address resolution protocol helps user get the MAC address of a device through its IP address.
Under TCP/IP network environment, each host is assigned with a 32-bit IP address, but MAC address
needs to be known for message transmission in the physical network. ARP is a tool that converts IP
address into MAC address.
