VPN, or Virtual Private Network, technology allows you to connect computers or whole networks to remote networks which cannot be accessed in any other way. VPN tunnels provide secure traffic transfer which is isolated from other computers or networks by data encryption.  
You can create and manage VPN tunnels in CONTROL PANEL. The total number of tunnels is limited to 20.

Log in to CONTROL PANEL and navigate to Services > Cloud Server > VPN.

  • The tunnels are displayed by their names. Click the name of a tunnel to view the properties of the remote network and click Configuration Instructions to get the information you will use to set up connection on the remote network end:

  • Each tunnel has the following options:
    • Enable
    • Disable
    • Delete
      The availability of the options Enable and Disable depends in the current tunnel state. You can delete any tunnel anytime.

  • The tunnels can be Enabled or Disabled. If you create a new tunnel or change the state of an existing tunnel it becomes Updating. Click Refresh on top of the page to view the current state.

  • To create a new tunnel click Add new tunnel on top of the page and spesify the party's settings.
    • Tunnel Name: Specify the tunnel name as it should appear in Smarsh Hosted Services.
    • Description: Add a description if necessary.
    • Peer IP: Enter external IP of the VPN endpoint/appliance.
    • Peer Network: Enter gateway IP of the remote peer subnet
    • Encryption Protocol: Select desired encryption protocol:

    • MTU: Specify Maximum transmission unit.
    • Open VPN Tunnel: Use the option Open VPN Tunnel to create a tunnel for all private network, i.e. for all of your Cloud servers. If this option is not selected a VPN tunnel is created for one Cloud server only.
