in USG FLEX H Series

Installed USG Flex 500H quite standard with SSL VPN and using OpenVPN: Upload large file from device to server - about 0.5 - 1 Mb/Sec. Download about 3 - 4 Mb/Sec.

Are there any special settings to achieve available bandwidth?

    Hi @JJ9231,

    Here is the official test report for your reference. You can disable security policy and all security services to check the throughput again.

    Using HTTP protocol to get 700M ZIP file from a server.
    SSL VPN (AES) throughput on USG FLEX 500H with firmware 1.20 is around 239.5 Mbps.
    (Security policy, Security services, BWM, DOS, Session control are disabled.)
