Configuration overview and prerequisites
Prerequisites:
- Two RUTX routers
- 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 (RUTX) acts as the OpenVPN server and other RUTX acts as client. OpenVPN connects the networks of HQ Office and Remote Office. Remote Office will also have a separate WiFi AP for guests.
When the scheme is realized, remote office workers will be able to reach HQ’s internal network with all internal systems by connecting to the router via LAN port or by connecting to WiFi AP, which is used for work. All remote office's WAN and LAN traffic is going to travel through VPN tunnel. There will also be a separate WiFi AP for guests, by connecting to it they will only be able to reach WAN, but they won't be able to reach HQ’s internal network.
Configuring HQ office router
Before you start configuring the router turn on "Advanced WebUI" mode. You can do that by clicking the "Basic" button under "Mode", which is located at the top-right corner of the WebUI.
Note: You will need to do that in both, HQ and remote office routers.
OpenVPN
Generating Static key
Login to the router's WebUI, navigate to the Services → CLI page and do the following:
|
Write the following commands to create OpenVPN Static key, which will be used for authentication: 1) cd /etc/easy-rsa 2) openvpn --genkey --secret static.key |
Extracting the key
Linux
If you are using a Linux-based OS, extracting files from the router is simple. Just go to the directory on your PC where you want to relocate the files, right click anywhere and choose the Open in Terminal option. In the Terminal command line use the Secure Copy (scp) command to copy the files from the router. The full command should look something like this:
$ scp [email protected]:/etc/easy-rsa/static.key ./
The [email protected]:/etc/easy-rsa/static.key specifies the path to where the Static key is located (replace the IP address with your router's LAN IP); the ./ denotes that you want to copy the contents to the directory you are in at the moment.
Windows
If you are using Windows, you can copy files from the router using WinSCP, an Open source freeware SFTP, SCP and FTP client for Windows OS. Use the same login information with WinSCP as with CLI or SSH. Please note: You must select SCP as File Protocol in WinSCP Session settings. |
Once you've connected to the router with WinSCP, copying the files should be simple enough: just go to /etc/easy-rsa/, select the Static key file and drag it to directory on your PC where you would like to store it. |
Configuring OpenVPN server
Now go to Services → VPN → OpenVPN. There create a new configuration by writing New configuration name, selecting role Server and pressing Add button. It should appear after a few seconds. Then press Edit. |
Now apply the following configuration:
|
Configuring remote office router
Before you start configuring the remote office router, set a static IP address on the device you are configuring the router with (e.g. 192.168.1.10). You can find instructions on how to do that here:
Note: make sure to switch back to automatic DNS and IP address obtaining when you are done configuring the router.
OpenVPN
LAN
Go to Network → Interfaces and press Edit next to your LAN interface: |
Apply the following steps:
|
Configuring OpenVPN client
Go to Services → VPN → OpenVPN. There create a new configuration by writing New configuration name, selecting role Client and pressing Add button. It should appear after a few seconds. Then press Edit. |
Now apply the following configuration:
|
Guest WiFi
Creating a new WiFi AP
Editing Firewall rules
Results
Remote office should now be able to access HQ network resources. To verify the connection you can ping remote RUTX 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. |
