Netmask
Default
255.255.255.0
Options
Netmask setting (e.g., “255.255.0.0”)
Description
This field is for the subnet mask. A subnet mask represents all of the network
hosts at one geographic location, in one building, or on the same local area
network. When a packet is sent out over the network, the WE-2100T module
will use the subnet mask to check whether the desired TCP/IP host specified in
the packet is on the local network segment. If the address is on the same
network segment as the module, a connection is established directly from the
module. Otherwise, the connection is established through the gateway as
specified in the “Gateway” parameter.
Gateway
Default
Options
IP address (e.g., “192.168.1.1”)
Description
This field is for the IP address of the gateway, if applicable. A gateway is a
network computer that acts as an entrance to another network. Usually, the
computers that control traffic within the network or at the local Internet service
provider are gateway nodes. The WE-2100T module needs to know the IP
address of the default gateway computer in order to communicate with the hosts
outside the local network environment. Consult your network administrator if
you do not know how to set this parameter.
