I have tried to install service application only on remote computer and to manage trafice remotely. So what acctually happened - whole trafic compleately stopts and it is not possible to use internet or any other TPC/IP based protocol on computer.
What is strange that the same thing worked on onother computer.
Perhaps because of some third-party traffic filtering programs like an antivirus or firewall. At the moment we know that the SoftPerfect Bandwidth Manager is not compatible with Sygate personal firewall.
