A VPN is a private network that uses a public network (usually the Internet) to connect to devices with Private IP addresses from a machine through your LAN or from home.

The VPN tunnel would be used for those who have a private IP address on their SIMs.

What is a site-to-site VPN tunnel?

A site-to-site VPN tunnel is an network environment where two firewalls are used to create a VPN tunnel. By Wireless Logic, we use IPSEC VPN tunnels. We configure a firewall on our side and then send the config parameters to customer. The customer then need to enter the config parameters onto their firewall/router. This would enable any machine(s) on a company’s LAN to connect to its devices with our m2m SIMs and vice versa. This is an always-on VPN connection. To create a site-to-site tunnel, customers need to have a hardware firewall/router which is capable of setting up an IPSEC VPN tunnel.
