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 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.
Underlying Connection Specify the underlying connection above which the pro-
tocol will be initiated.
Internet Protocol Select one of the following Internet protocol options from the
'Internet Protocol' combo-box:
 Unnumbered
 Obtain an IP Address Automatically
 Use the Following IP Address
Please note that the screen will refresh to display relevant configuration settings
according to your choice.
Unnumbered Select this option to assign a predefined LAN address as Wat-
son's WAN address. This is useful when Watson operates in routing mode. Be-
fore selecting this option, configure the 'Internet Protocol' of your LAN device (or
bridge, in case the LAN device is under a bridge) to use a permanent (static) IP
address from the range of IP addresses provided by your ISP (instead of
192.168.1.1).

Obtain an IP Address Automatically Your connection is configured by default
to obtain an IP automatically. You should change this configuration in case your
service provider requires it. The server that assigns the gateway with an IP ad-
dress, also assigns a subnet mask. You can override the dynamically assigned
subnet mask by selecting the 'Override Subnet Mask' and specifying your own
mask instead.
