"Untangle supports OpenVPN's site-to-site and client-to-site
configurations. Site-to-site means you can create a secure tunnel
between your different offices or locations via the Internet, so
you can share files and resources between them all. Client-to-site
means you can offer connections to remote users, so they can
securely access their files or so they can encrypt their Internet
traffic from Wi-Fi eavesdroppers when they're using hotspots. We'll
set up both solutions.
"First, you must setup the OpenVPN server. If doing site-to-site
connections, you just need to do this at one location, such as your
main office. Then we'll configure another Untangle machine as a VPN
client or site at the other locations. If you're offering only
remote access to individuals, you can configure an Untangle machine
as the server at any location. Then we'll install and configure the
OpenVPN client program onto the desired computers."
