You can setup IP-blocking on this website: https://security.wmtransfer.com (IP blocking).
After IP blocking has been enabled, WebMoney Keeper will only run on computers with IP-addresses matching the range of addresses and subnets you provided.
When WM Keeper attempts to connect to the server on an unauthorized IP-address, IP-unblocking instructions will be sent to the e-mail address you included on the setup page.
For this purpose we recommend using an e-mail address different from your WM-ID registration address.
Contact your ISP administrator to find out your IP-address and the subnet mask.
If you have any questions about IP blocking, contact our technical support: support@wmtransfer.com.
