The Routing page allows you to define the output interface for specific destinations (IP and Subnets).
The Current Routing Table displays the output from the
route system command.
A default table entry should be present which indicates traffic going towards the Internet.
The Static Routing Table is manually created. Here, you can define static routes (with their netmask/gateway) towards specific destinations. While not commonly needed on simple networks, this may be useful for advanced setups such intranets, VPNs, and so on.
If the WAN interface is assigned IP addressing via DHCP, this options specfies whether or not to accept routing information from the DHCP server. Such routing information is usually sent via DHCP option 33 or 121.
