Introduction

Most of us are aware, that network security is extremely important. If your WiFi network is not properly secured, it makes you and all of your home or office resources vulnerable to a variety of security threats. To stay ahead of the curve, many companies and home users have guest WiFi. Unlike your regular WiFi network that you or your company members use, the guest WiFi network restricts what your guests can do in your network. It gives visitors access to the Internet connection, but nothing else making you or your company a lot more secure. This chapter is a guide on configuring a guest WiFi.

Results

If you've followed all the steps presented above, your configuration should be finished. If you are near a RUT, that is, in a wireless zone, turn on WiFi on your device and view the available networks. You should see the available SSID - "RUTX_WiFi_2G" and "Guest_WiFi". Select one of them and enter the appropriate WiFi password.

Wireless users connected to SSID: “RUTX_WIFI”, will be assign to “LAN”, and will get IP from main pool 192.168.1.0/24.

Wireless users connected to SSID: “GUEST'S_WIFI”, will be assign to LAN “Guest”, and will get IP from new pool 10.10.10.0/24.

Guest hosts are unable to access any data from pool 192.168.1.0/24.

---

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, that belong to the work network (192.168.1.0/24), should now be leased to LAN devices by HQ router.

In order to check the guest WiFi, you simply need to connect to the newly created WiFi AP, then check whether you have internet connectivity and try to ping OpenVPN server LAN IP - if everything is set up correctly, you should not be able to do that.
