The main duty for a router is to look for an optimal transfer
path for each data packet passing through it, and transfer it to the
specified destination. So, it's essential for the router to select an
optimal path, i.e. routing algorithm. To complete this work, the
router stores the related information of various transfer paths, i.e.
establishing a routing table, for future route selection.

Destination Network IP Address: Enter a destination IP
address or subnet.
Subnet Mask: Enter a Subnet Mask that corresponds to
destination IP address or subnet you entered.
Gateway: Next-hop IP address.
1. Gateway IP address must be on the same subnet with
LAN/WAN IP address.
2. If Destination IP address box is entered with a single IP
address, then corresponding subnet mask must be set to
255.255.255.255.
