Sometimes you want to use Statistica from somewhere else via a VPN-Connection. Some solutions, for instance, Direct Access, are operating with IPv6-protocols, which is so far not compatible with Concurrent Statistica-License Management. As license server can't be reached, Statistica is not usable.
This functionality should be added in future releases as IPv-6 environment will become more common. Apparently the Flex-LM already supports IPv6 and it just has to be activated.
