¾  Subnet Mask:  The network portion of the 
Destination LAN IP. 
¾  Gateway: The gateway of the next hop, usually 
the Router or host’s IP address. 
Note: 
1. The gateway must keep the same segment with the 
Router’s LAN IP address. 
2. If the destination IP address is one host’s IP address, 
the Subnet mask should be 255.255.255.255. 
3. If the destination IP address is an IP address range, 
the subnet mask should match the IP address. For 
example, if the IP is 10.0.0.0, subnet mask should be 
255.0.0.0; if the IP is 10.1.2.0, subnet mask should be 
255.255.255.0.
