Networking rut configuration example openvpn bridge use case topology v1.png

Configuration overview and prerequisites

Prerequisites:

  • One RUTxxx router
  • A Public Static or Public Dynamic IP addresses
  • An end device to configure the router (PC, Laptop, Tablet, Smartphone)

The topology above depicts the OpenVPN scheme. The router with the Public IP address ({{{name}}}) acts as the OpenVPN server and other {{{name}}} acts as client. OpenVPN connects the networks of HQ Office and Remote Office.

When the scheme is realized, remote office workers will be able to reach HQ’s internal network with all internal systems, allowing working from remote office to be possible. All remote office's WAN and LAN traffic is going to travel through VPN tunnel.

Configuring HQ office router

OpenVPN

Login to the router's WebUI, navigate to the Services → CLI page and do the following:

  1. Enter username root .
  2. Write the Password of your router.

Write the following commands to create and open OpenVPN Static key, which will be used for authentication: 

1) cd /etc/easy-rsa
2) openvpn --genkey --secret static.key
3) cat static.key

Now apply the following configuration:

  1. Enable instance.
  2. Set TUN/TAP to TAP (bridged).
  3. Enable LZO.
  4. Select Authentication: Static key.
  5. Add Keep alive interval: 10 120.
  6. Upload Static pre-shared key (use the .txt file you created in previous steps).
  7. Save the changes.

Configuring remote office router

OpenVPN

Now apply the following configuration:

  1. Enable instance.
  2. Set TUN/TAP to TAP (bridged).
  3. Enable LZO.
  4. Select Authentication: Static key.
  5. Write Remote host/IP address (RUTX OpenVPN server public IP).
  6. Add Keep alive interval: 10 120.
  7. Upload Static pre-shared key (use the .txt file you created in previous steps).
  8. Save the changes.

LAN

Apply the following steps:

  1. Change your LAN IP address to: 192.168.1.2
  2. Disable DHCP.
  3. Save the changes.

Results

Remote office should now be able to access HQ network resources. To verify the connection you can ping remote RUT HQ server LAN IP and if you get a reply, you have successfully connected to HQ‘s internal network. Also, all LAN addresses should now be leased to the LAN devices by HQ router.
