Security
Login Failures
For increased security, administrators can set policies governing user log in failures. Check the Enable
checkbox (the default is enabled).
Note: If Login Failures is not enabled, users can attempt to log in an unlimited number of
times with no restrictions. For security purposes, enable the function and lockout policies.
Filter
IP and MAC Filtering
Control access to the KVM switch based on the IP and/or MAC addresses of the client computers
attempting to connect. A maximum of 100 IP filters and 100 MAC filters are allowed. If any filters have
been configured, they appear in the IP Filter and/or MAC Filter list boxes.
To enable, click to put a check mark in the IP Filter Enable and/or MAC Filter Enable checkbox.
• If the Include button is checked, all the addresses within the filter range are allowed access; all
other addresses are denied access.
• If the Exclude button is checked, all the addresses within the filter range are denied access; all
other addresses are allowed access.
Adding Filters
To add an IP filter:
1. Click Add to open the dialog box.
2. Specify an IPv4 or IPv6 address.
3. Enter the address you want to filter in the From: field.
– To filter a single IP address, click to put a check in the Single IP checkbox.
– To filter a continuous range of addresses, enter the end number of the range in the To: field.
Note: This description is for the AP GUI. The Browser GUI does not offer an IPv4 or
IPv6 choice. It only has From and To fields for IPv4 filtering and does not have a
checkbox to specify a single IP address. To filter a single IPv4 address, enter the same
address in both From and To fields.
4. After filling in the address, click OK.
5. Repeat the steps to filter additional IP addresses.
