Overview
You may already know about the User/Devices differences in Licensing and you wish to prevent users from connecting with multiple devices at a time to Kerio Control. However, Kerio Control does not directly support this feature. A possible workaround is to block specific devices by filtering their MAC addresses.
Solution
While not possible to prevent specific users to simultaneously login to Kerio Control using multiple devices, you can restrict a user's access to a single of his devices by blocking those specific devices via their MAC addresses. Follow the steps for Filtering MAC addresses in Kerio Control, while choosing the desired filtering approach:
- Prevent listed computers from accessing the network — The filter blocks only MAC addresses included in the list. This mode can be used to block known MAC addresses but does not filter traffic of new, unknown devices.
- Permit only listed computers to access the network — The filter allows only MAC addresses included in the list, any other address is blocked. Select the Also permit MAC addresses used in DHCP reservations or automatic user login option if you use automatic user login and DHCP reservation by MAC. MAC addresses allowed by automatic user login and DHCP reservations are not visible in the MAC addresses list (see below).
Please note that this is a workaround and not a direct feature of Kerio Control.
Summary
While Kerio Control does not directly support limiting a user's access to a single device at a time, a possible workaround is to block specific devices by filtering their MAC addresses in the 'Security Settings' section.
