will allow you to choose between the available rules. To learn how to configure
scheduler rules, refer to Section 9.9.3.
Network Select whether the parameters you are configuring relate to a WAN,
LAN or DMZ connection, by selecting the connection type from the drop-down
menu. For more information, refer to Section 9.4.2.
MTU MTU is the Maximum Transmission Unit. It specifies the largest pack-
et size permitted for Internet transmission. In the default setting, Automatic, the
gateway selects the best MTU for your Internet connection. Select 'Automatic' to let
Watson find the optimal MTU value for your connection. In case you select 'Manual'
it is recommended to enter a value in the 1200 to 1500 range.
Internet Protocol The local IP address for the interface.
9.4.16.4 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.
Routing Information Protocol (RIP) Select this check box to enable the
Routing Information Protocol (RIP). RIP determines a route based on the smallest
hop count between source and destination. When RIP is enabled, select the follow-
ing:
 Listen to RIP messages—select 'None', 'RIPv1', 'RIPv2' or 'RIPv1/2'.
 Send RIP messages—select 'None', 'RIPv1', 'RIPv2-broadcast' or 'RIPv2-
multicast'.
