Distributed server functionality for emulated LAN

A system for emulating a local area network connected to a global communication network, acting as a backbone network comprising clients units and a server which are connected to said global network, and a broadcast functionality (BUS) for relaying messages to all clients in the emulated local area network, wherein said BUS functionality is distributed and implemented in more than one network unit node in the emulated local area network, wherein said system also is used for establishment of one or several Virtual Private Network (VPN) connections, the system comprising an end user client device and a VPN access server communicatively connected to the end user client via said global network, wherein a standalone VPN client device is interconnecting the end user client with said global network,

• wherein said VPN client comprising monitoring means for monitoring all traffic between the end user client and the VPN server;
• wherein said monitoring means are devised to detect when a handshake agreement is established between the end user client and the VPN server;
• wherein said monitoring means are devised to determine said handshake agreement for the initialisation phase of said VPN access acquiring session as completed upon detecting that said server acknowledges said end user client as a confirmed user;
• and
• wherein said VPN client is devised to request, upon detection of a completed handshake and execution of said VPN setup session overtake, said server to distribute VPN configuring data relevant for the inclusion of said end user client into said virtual private network.
