Slow bandwith with SSL VPN over FortiGate 90E

Hi there,

We are using the FortiGate 90 firewall to connect to a data center for working with remotedesktop connection on two Windows terminal server (loadbalancing). Our internet provider is Unitymedia Germany with 400/25 Mbit/s. With this setup we get only 10Mbit/s download and upload. We could not find out why this bandwith limitation occurs.

The data center has checked the settings in the firewall but coul not find any problems. Unitymedia also says that they not throttle any internet connections.

Do anyone have the same issues or can someone tell me how we can look for the issue?

Regards,
