route.
 Subnet Mask: The   network   portion   of   the 
Destination LAN IP.
 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 WAN 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.

15.1 Time Settings
This   section   is   to   select   the   time   zone   for   your 
location. If you  turn off  the Router,  the settings for 
time disappear. However, the Router will automatically 
obtain the GMT time again once it has access to the 
Internet.
