Performance Issues with EMS FortiVPN Client – Free Client Works Fine

[leo-ehk]

Hello Community,

we have several employees experiencing severe performance issues with the Forti EMS Client 7.2.8, particularly when accessing internal websites via VPN and using applications like SAP GUI. In some cases, connections even drop unexpectedly.

Even after reinstalling the client, the problem persists. However, when switching to the free Forti VPN Client, the issues disappear immediately, and everything runs smoothly.

Our environment:
- In-house EMS Server 7.2.8 with FortiClient 7.2.8
--FortiGate connected via IPv4 only (IPv6 is disabled on WLAN and VPN adapters)
- Only SSL VPN is used; all other VPN options are disabled

Does anyone have an idea? Many thanks in advance!

The only strange thing is that there are no problems with the free client.

For me it is not so strange. Free version is basic compared to full versions. They are simply different software and deal differently with VPN in many aspects.
