9.4.3.3 Routing
You can choose to setup your gateway to use static or dynamic routing. Dynamic
routing automatically adjusts how packets travel on the network, whereas static
routing specifies a fixed routing path to neighboring destinations.
Routing Mode Select one of the following routing modes:
 Route Use route mode if you want your gateway to function as a router be-
tween two networks.
 NAPT Network Address and Port Translation (NAPT) refers to network ad-
dress translation involving the mapping of port numbers, allowing multiple ma-
chines to share a single IP address. Use NAPT if your LAN encompasses mul-
tiple devices, a topology that necessitates port translation in addition to address
translation.
Device Metric The device metric is a value used by the gateway to determine
whether one route is superior to another, considering parameters such as band-
width, delay, and more.
Default Route Select this check box to define this device as a the default
route.
Multicast – IGMP Proxy Default IGMP proxy enables the system to issue IGMP
host messages on behalf of hosts that the system discovered through standard
IGMP interfaces. IGMP proxy enables the routing of multicast packets according to
the IGMP requests of LAN devices asking to join multicast groups. Select the 'Mul-
ticast IGMP Proxy Default' check box to enable this feature.
