VPN software for all hardware and software platform

  How this VPN works is of the following: For instance, if the Australian branch in Sydney decides to contract a supplier, then the London office might need to know that immediately.   The main part of IT infrastructure is set up data hosted on Seoul.  In Singapore there are twenty people whose work depends on the availability of the data hosted on Seoul servers. The said scenario is depicted in Figure 2.  Both sites are equipped with a permanent Internet line.  An internet gateway router is set up to provide Internet access for the staff.  This router is configured to protect the local network of the site from unauthorized access from the other side, which is the "culprit"Internet.   Such a router set up to block special traffic san be called firewall and must be found in every branch that is supposed to take part in the VPN.  The software used for VPN must be installed on this firewall.  Many modern firewall appliances from manufacturers like Bin Tec or Cisco includes this feature and there is VPN software for all hardware and software platform.   Once connection has been established, the company has a working Virtual Network.  The two branches are connected via internet and can work together in a real network.  Here, a VPN without privacy, because any internet router between Seouland Singapore can read the data exchanged.  A competitor gaining control over an internet router could read all relevant business data going through the virtual network.
