The topology above depicts the L2TP/IPsec scheme. The router with the Public IP address ('''RUTX''') acts as the '''L2TP/IPsec server''' and the '''Android device''' acts as '''client'''. L2TP connects the networks of '''RUTX''' and '''Android client''', IPsec provides the encryption for the L2TP tunnel. Created VPN tunnel will allow Android device to reach home network behind the RUTX router, but the rest of Android device network traffic will not be redirected through VPN. This way the VPN tunnel will not be under a huge load and will provide greater speeds.

When the scheme is realized, you will be able to log on to your home network from anywhere - work, hotel, car. You will have access to all of your home resources, and your data will still be secure, even if you will be using public WiFi.

Networking RUTX VPN between HQ topology v3.png

Configuration overview and prerequisites

Prerequisites:

  • One RUTX router of any type
  • A Public Static or Public Dynamic IP address
  • At least one Android device

The topology above depicts the L2TP/IPsec scheme. - The router with the Public IP address (RUTX11) acts as the L2TP/IPsec server and the Android device acts as client. L2TP connects the networks of RUTX11 and Android client, IPsec provides the encryption for the L2TP tunnel. Only LAN traffic is going to go through that tunnel, any other WAN traffic won't go through it. This way the VPN tunnel will not be under a huge load and will provide greater speeds.

When the scheme is realized, you will be able to reach your home internal network with all internal systems, cameras, or other IOT devices, from anywhere in the world.

Configuring home router (RUTX)

L2TP

Networking rutos configuration example l2tp over ipsec android 1 v1.png

Login to the router's WebUI and navigate to the Services → VPN → L2TP page and do the following:

  1. Select Role: Server.
  2. Enter a custom configuration name.
  3. Click the Add button.
  4. Click the Edit button next to the newly created L2TP instance.

  1. Enable the L2TP instance.
  2. Enter a User name and Password for authentication for the client.
  3. Optionaly, set a fixed IP for this client (if left empty, client will receive first free IP from the IP range).
  4. Don't forget to Save the changes.

IPsec

Go to the Services → VPN → IPsec page and do the following:

  1. Enter a custom name for the IPsec instance.
  2. Click the Add button.
  3. Click the Edit button next to the newly created instance.

In the IPsec Configuration page, do the following (and leave the rest as defaults, unless your specific configuration requires otherwise):

  1. Enable the instance.
  2. Enter your Pre-shared key.
  3. Select Type: Transport.
  4. Save changes.

Android phone

Configure the following parameters:

  1. Select VPN provider: Windows (built-in).
  2. Enter a custom Connection name.
  3. Enter the router's WAN IP address into the Server name or address field.
  4. Select VPN type: L2TP/IPsec with pre-shared key.
  5. Enter the Pre-shared key exactly as it was specified on the router.
  6. Select Type of sign-in info: User name and password.
  7. Enter the User name and Password exactly as they were specified on the router.
  8. Click Save

Home worker should now be able to access HQ network resources. To verify the connection you can ping some internal HQ server and if you get a reply, you have successfully connected to HQ‘s internal network.
