IMPORTANT! Don't setup your Mikrotik RouterOS remotely. You have to be connected via the LAN interface, otherwise you will cut the connection (access to the router) and you will not be able to access it remotely any more.
Please mind that this guide is for a router at factory setting.
Connect to your Mikrotik via WinBox. If you don't have Winbox, you can download it here: WinBox
You will need the default gateway IP address of your Internet provider (ISP) and VPN Office IP address (please contact us if you do not know your VPN Office IP addresses).
