It first opens an UDP connection on port 137 and. and I'm having severe problems making a firewall rule to let it work correctly. However, now he needs to install the VPN client on a machine which isn't running Windows 10, and the "regular" Windows client for FortiGate is some kind of on-line installer. With that installed, once I was at the office, I was able to add an exception to our Sophos UTM and allow him to connect. Eventually he installed the Windows 10 "store" client.

However, a coworker had problems getting the VPN client to install at all (I wasn't around to help at the time).

One of our customers is running FortiGate and if we want to connect to them? Well, we need to use FortiClient.
