Sinkhole mitigation by IP address, domain, or country
If you would like sinkhole protection to be applied to specific IP addresses, domains, and/or countries, use the MTD threat management console Network Sinkhole Settings to define them.
MTD Sinkhole Local Actions must be enabled to deploy the MTD threat management console sinkhole. See Enable sinkhole VPN mitigation for iOS devices. The MTD console Sinkhole feature is optional, and MTD sinkhole will continue to work in either case.
