      @Aaron: Windows by default uses the port 1723 for VPN. to change that port on client side:
      1. Open registry editor and navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0003
      2. At the right pane double click to open the "TcpPortNumber" value. Change to Decimal and at the value data change the 1723 port to the new port.
      3. Close registry editor and restart the computer.
      p.s. keep in mind that the change will affect all VPN connections on the machine.
