Allows you to specify a default Gateway address. This must be in 32-bit dotted-decimal notation.
The default gateway is the route to all networks. The default Gateway address informs each personal computer or other network device where to send data if the target station does not reside on the same subnet as the source. If your machine can reach all stations on the same subnet (usually a building or a sector within a building), but cannot communicate outside the area, it is usually because of an incorrectly configured default gateway.
If you do not know or are not sure of your Gateway Address, contact your network or system administrator.
