MikroTik 6 L2TP VPN Setup Tutorial

I will reveal the secret to you. We need to make the IPSec part manually. This is very similar with this scenario when one side is behind the NAT.

But you will see. The first step is the same. Open the PPP menu. We will again select the L2TP client. Fill all necessary fields and click on the button [ Apply ].

Mikrotik will create the new VPN interface and in the short while, we will see the connection status update. Alas, we have the tunnel without encryption. We knew how to setup the IPSec tunnel.

Therefore, we will configure it in a minute. The best way is to fill one document about your IPSec configuration. We need to define the IPSec peer.

The biggest change here is that the mode of IPSec operation is main l2tp. The next step is the IPSec policy. We need to make it manually, too. This is the transport mode. Therefore, the source address will be the same as the SA source address.

On the Action tab we must enter the same IPs as on the General tab. In addition, we need to leave the checkbox Tunnel unchecked. Please, pay attention that you will use the Default proposal here. If you like, you can specify the port number on the General tab on the client router. In the end of this article, we will make a short analysis of the network ports used for these network connections. Every protocol has its number. This connection will use the port for communication.

Furthermore, both sides use the same port number. This is the second communication channel. Again, both sides use the same port number. And the third channel of communication is between devices exchanging the IPSec traffic. In our case, those devices are routers themselves. Unrelated to the IPSec tunnel mode, this third channel will use one of two specific protocols.

In most cases we will use the ESP protocols, as we can encrypt the payload. Check that these ports and protocols are allowed to input into the device. In case that they are not explicitly enabled in the firewall rules, your router will block them.

Both client are connected at VPN server with different sub network.
