44 Chapter 2 - IP Routing & Bridging
IP Address
This is the IP address of the IPSec port. It should be entered as four decimal
numbers separated by periods -- for example, 198.238.9.5
v Note: This IP address must be on the same IP network as the IPSec
Gateway, which is configured using the IPSec Gateway Dialog Box (under
Global/IPSec Gateway).
Network IP Subnet Mask
The subnet mask value is used to tell the router what part of the IP address
identifies the network segment (the “network” portion), and what part identi-
fies individual interfaces (the “host” portion).
If you do not enter a number in the Subnet Mask field, CompatiView will
derive a default value from the IP Address number you entered just above.
This default assumes you want a single subnet for all of the available host
addresses. You must manually set the field if you want to further divide the
address range.
To have CompatiView calculate a default mask, make sure that the Subnet
Mask field is empty, position the cursor in the IP Address field, then just tab
through the Subnet Mask field.
Network IP Broadcast Address
The router will use this address to send any IP broadcast messages. To have
CompatiView calculate a default broadcast address, make sure that the
Broadcast Address field is empty, position the cursor in the Subnet Mask
field, then just tab through the Broadcast Address field.
