You can ping far side of vpn connection. Details of WMI Win32_PingStatus you can find here:
http://msdn.microsoft.com/library/aa394350(v=VS.85).aspx
Vba version:
Sub test()
If Ping("192.168.2.2") Then
    MsgBox "Passed", vbOKOnly
Else
    MsgBox "Failed", vbOKOnly
End If
End Sub
Public Function Ping(ByVal ComputerIP As String) As Boolean
    'You can use also name of computer
    ' Return TRUE, if pin was successful
   Dim oPingResult As Variant
    For Each oPingResult In GetObject("winmgmts://./root/cimv2").ExecQuery _
        ("SELECT * FROM Win32_PingStatus WHERE Address = '" & ComputerName & "'")
        If IsObject(oPingResult) Then
            If oPingResult.StatusCode = 0 Then
                Ping = True
                'Debug.Print "ResponseTime", oPingResult.ResponseTime 'You can also return ping time
               Exit Function
            End If
        End If
    Next
End Function

nm, this worked for now.
Function IsVPNConnected()
   
   IsVPNConnected = False
   sComputer = "."

   Set oWMIService = GetObject("winmgmts:\\" _
    & sComputer & "\root\CIMV2")

   
   Set colItems = oWMIService.ExecQuery( _
    "SELECT * FROM Win32_NetworkAdapterConfiguration", , 48)

   
   For Each objItem In colItems

'Please check description of your VPN Connection by running command "ipconfig /all" on command-line.

    If (InStr(objItem.Description, "AnyConnect")) Then
     IsVPNConnected = objItem.IPEnabled
    End If

   Next
   

   If (IsVPNConnected) Then
    IsVPNConnected = MsgBox("I am Connected to VPN.")
   Else
    IsVPNConnected = MsgBox("I am Not Connected to VPN.")
   End If

End Function
