Restrict access to this page security group to specific IP addresses: This capability is most useful for restricting access from a public computer lab. To restrict access based on IP address, do the following:
Tick Restrict IP.
Under Allowed IP Ranges, enter the allowable IP addresses. You can enter the addresses individually. For example, if you wanted to define access for a lab with IP addresses 138.234.161.001 to 138.234.161.015, you could Add each of these IP addresses individually. You can also limit access with partial IP specifications. For example, if you enter 138.234.161 (with no period at the end), access will be restricted to the range of IP addresses from 138.234.161.000 to 138.234.161.999. After entering each address specification, click Add.
