Posts ago we already discussed aboutvpn, on this occasion I will share the advantages and disadvantages of vpn. Of course the private network within the public network has its own advantages and disadvantages, but the benefits are definitely greater than losses, clothes olh, therefore, let us refer to reviews of the following:

Profits or benefits of VPN

Some advantages of VPN technology include:

Lack or weakness of VPN

Any excess drawback, there is definitely some disadvantages of VPNS of which are:

• internet connection (public network) we cannot predictions. It can maklumi us because we basically just "nebeng" network connection on the other side so that we don't have automated control over the network.

• more attention toward security. Again due to the use of public networks, then we need to give more attention to prevent the occurrence of such things as unwanted eavesdropping, hacking and cyber crime action network VPN.

• fine and I do not understand

The workings of the VPN (with PPTP Protocol) is as follows:

• VPN requires a server that acts as a liaison between the PC, this could either be the VPN Server computer with VPN Application Server or a Router.

• to start a connection, a computer with VPN Client application contacts the VPN Server, the VPN Server then verifies the username and password and if successful then the VPN Server provides a new IP Address on the client computer and then a connection/tunnel is formed.

• Next the client computer can be used to access the resource (computer or LAN) located behind the VPN Server instance to transfer data, ngeprint dokument, browsing with the given gateway from the VPN Server, do remote desktop etc.

Such an explanation of the advantages and disadvantages of VPNs from me. If there is a less obvious please give us a comment. Thank you.
