Dynamic routing automatically adjusts how packets travel on the network, whereas static
routing specifies a fixed routing path to neighboring destinations.

Parameter Description
Routing Select 'Advanced' or 'Basic' routing.
Routing Mode Select one of the following Routing modes:

Route: Use route mode if you want your device to function as a router
between two networks.

NAT: Network Address Translation (NAT) translates IP addresses to a
valid, public address on the Internet. This adds security since internal LAN
addresses are not transmitted over the Internet. In addition, NAT allows
many addresses to exist behind a single valid address. Use the NAT routing
mode if your LAN consists of a single device, otherwise collisions may
occur if more than one device attempts to communicate using the same
port.

NAPT: Network Address and Port Translation (NAPT) refers to network
address translation involving the mapping of port numbers, allowing multiple
machines to share a single IP address. Use NAPT if your LAN
encompasses multiple devices, a topology that necessitates port translation
in addition to address translation.
Device Metric The device metric is a value used by the device to determine whether one
route is superior to another, considering parameters such as bandwidth, delay,
and more.
Default Route Select this check box to define this device as a the default route.
