Chapter 5 Settings for Interfaces and Network Services
First address, Last address
First and last address of the new scope.
Note: If possible, we recommend you to define the scope larger than it would be defined for the real number of users within the subnet.
Subnet mask
Mask of the appropriate subnet. It is assigned to clients together with the IP ad- dress.
Note: The Administration Console application monitors whether first and last ad- dress belong to the subnet defined by the mask. If this requirement is not met, an error will be reported after the confirmation with the OK button.
Lease time
Time for which an IP address is assigned to clients. This IP address will be auto- matically considered free by expiration of this time (it can be assigned to another client) unless the client requests lease time extension or the address release.
Exclusions
WinRoute enables the administrator to define only one scope in within each subnet. To create more individual scopes, follow these instructions:
•create address scope covering all desired scopes
•define so called exclusions that will not be assigned
Example: In 192.168.1.0 subnet you intend to create two scopes: from 192.168.1.10 to 192.168.1.49 and from 192.168.1.61 to 192.168.1.100. Ad- dresses from 192.168.1.50 to 192.168.1.60 will be left free and can be used for other purposes.
Create the scope from 192.168.1.10 to 192.168.1.100 and click on the Exclusions button to define the scope from 192.168.1.50 to 192.168.1.60. These addresses will not be assigned by the DHCP server.
