IP Filtering
The Security page contains settings that allow you to control access to
the B064-Series KVM Switch.
• IP and MAC Filters control access to the B064-Series KVM Switch
based on the IP and/or MAC addresses of the computers attempting
to access the system. If any filters have been configured, they
appear in the IP Filter and/or MAC Filter list boxes.
• The Login String lets the Administrator specify a login string
(in addition to the IP address) that users must include when they
access the B064-Series KVM Switch remotely. Users must include
the forward slash and the string along when they specify the IP
address. For security purposes, we recommend that you change
this string from time to time. (For example, entering abcdefg in
the Login String field will require users to type in a URL similar
to 192.168.0.126/abcdefg to access the B064-Series KVM Switch
remotely)
Note: If no string is specified here, anyone can access the B064-
Series KVM Switch with a Web browser using the IP address alone.
This makes the installation less secure.
To enable IP and/or MAC filtering, click the IP Filter Enable and/or MAC Filter Enable checkbox. There are a maximum of 100 filters allowed
for each.
• If the include button is checked, all the addresses within the filter range are allowed access to the B064-Series KVM Switch; all other
addresses are denied access.
• If the exclude button is checked, all the addresses within the filter range are denied access to the B064-Series KVM Switch; all other addresses
are allowed access.
To add an IP filter:
1. Check the IP Filter Enable check box.
2. Click Add. A dialog box similar to the one below appears:
3. To filter a single IP address, key in the same address in both the
From and To fields. To filter a range of addresses, key in the starting
IP address in the From field and the ending IP address in the To
field.
5. After filling in the addresses, click OK.
6. Repeat these steps for any additional IP addresses you want to filter.
To delete an IP filter:
Select the desired IP filter from the list and click Remove.
To modify an IP filter:
1. Select the desired IP filter from the list and click Edit. An Edit
dialog box similar to the Add dialog box will appear.
2. Delete the old start IP address and replace it with the new one.
3. Delete the old end IP address and replace it with the new one. Click
OK .
Note: To block a computer from accessing the B064-Series KVM
Switch, you do not need to filter both its IP address and its MAC
address. Any computer blocked by an IP filter will be denied access to
the KVM switch, even if the computer is allowed to access the KVM
switch under the MAC filters that are set up.
