The initial investment needed to set up a remote access VPN is minimal and they can easily be scaled as a company grows and this is especially true if a VPN service provider is used.
Why is VPN important for business?
The most important benefit though is data security. When an offsite employee sends data through a VPN, it is encrypted, so even if a hacker is able to intercept that data, they won’t be able to use it. This is particularly important if an employee accesses their companies’ network using public Wi-Fi while traveling because traffic sent over these networks is usually not encrypted.

What is site to site setup?
A site-to-site setup is where two (or more) different networks are connected together using one OpenVPN tunnel. In this connection model, devices in one network can reach devices in the other network, and vice versa. The implementation of this is, for as far as Access Server is involved in this, relatively simple. The more difficult part comes when dealing with firewalls and security filtering options, and altering routing tables in routers and Internet gateways, as there are so many of them of various brands and models, that we cannot possibly document all of them. However, routers should all have one thing in common: the ability to route traffic using static routes. With that capability comes the means to send traffic from one network to another, through a gateway system that provides connectivity to the other network. An OpenVPN Access Server with a Linux VPN gateway client forms such a gateway system, to form a bridge between two networks. If your network equipment is then properly adjusted as well, then a site-to-site setup that works transparently for all devices in the two networks can be achieved.
What IP address does OpenVPN use?
With the new static routes in place, whenever traffic now arrives at the router that has as a destination an IP address somewhere in 172.16.0.0/20 or 10.0.60.0/24, it will know that it should forward this to the OpenVPN Access Server at IP address 192.168.70.222. It will then forward it to where it needs to go, as it knows how to contact those two subnets.
How to connect to ovpn on Linux?
Transfer this client.ovpn file to your Linux client system (with SCP or WinSCP or copying and pasting contents of the file in a text editor like nano) and place it in the /etc/openvpn/ directory. Rename the file to something like headquarters.conf. The filename is not particular important, but the extension must end with .conf for the OpenVPN daemon to pick it up. Now reboot the Linux client operating system. It should now automatically connect and you should be able to see this connection appear on the OpenVPN Access Server's Current Users overview.
How to install OpenVPN on Linux?
What you do need is the OpenVPN open source client program for Linux. On Ubuntu you can install this with the command apt-get install openvpn. With the client program now installed, it is going to check for any *.conf files in the /etc/openvpn/ directory and at system startup try to connect them and keep them connected. What we need next is to obtain the auto-login connection profile for the user account created for site-to-site connectivity, and save it in the /etc/openvpn/ directory. To do that we need to get the file first:
What is IP forwarding?
IP forwarding is the function in an operating system that allows it to accept an incoming network packet on one network interface, and if the destination is on another network, to forward it there.
